I'd love to be able to define alpha channels in my color schemes, preferably with the TextMate convention.
I really liked this about the old TM. I'm gushing over Sublime Text 2, this would be icing on the cake. I know it sounds fluffy, and I'd be lying if I didn't admit that was a large part of it, but it was pretty cool to see the photoshop rgb/hex beneath my window (it's a stretch, but trust me, this is a useful feature)
This is one of the first things I looked for when loading TM themes into ST2.
Then it wouldn't cost me any money to feed my unicorn. I'm a HUGE fan of open source, but I can't think of a single free app I would trust as much as I do ST2. Skinner is doing a fantastic job of keeping this up to date. When my biggest bitch about his software is that the background isn't transparent (and that may be it)...
I'm really happy with ST2. Every now and then I get nostalgic and open TM, but I'm sold on ST2 100%. However, I would like to note that TM didn't make the entire window transparent. That's ugly to a distracting degree, it just looks wrong. There is shareware out there which enables you to do this on the Mac.
What I want is just the background. Open terminal and set it pro and then adjust the background opacity, that's what I'm talking about.

So, is this feature being considered for upcoming releases, if so, when? If not, why?
Cheers

+1 - really need to be able to see windows in the background (it helps to observe terminal output, progress bars, and the like)
+1 Yes please. Totally useful feature, especially on smaller screens, when observing terminal output, color hex values, text on websites, emails, you name it. Plus it looks cool when you've got a nice wallpaper in the background :-)
+1
It's shameful that such a feature-rich app doesn't support this already!
This is the only reason I have not switched to ST2 because it doesn't support transparency. My Textmate theme uses transparency for almost all syntax (for example HTML attributes), and since ST ignores these it just ends up being a big grey blob.
Add this and I purchase ST2. I won't be switching until I can use my TM theme properly.
+1 for me too!!
Subtle but really opens up the desktop like mirrors in a room :)
Being able to set transparency for the background colour would be very nice. And as some other commented - I'd also prefer that the foreground colour (text colour) remains opaque.
Background transparancy and a hot key to toggle it would be money in this app.
This would make the shift from emacs on a transparent terminal to sublime text soo much easier...
+1... I was searching for this feature on net and landed here. If it can possible then please make it happen.
I also want a transparent bg!, it's very productive to be able to see your browser behind your editor.
+1 miss transparent background. everything else has it!
Would love to have ftp in the background and be able to see confirm auto uploading on saves. This feature would be especially useful to me when working remotely on my laptop, where screen space is limited.
+1 for background transparency!
Btw, I just found this plugin adjusting the transparency for Windows users posted by @SublimePackages: https://github.com/vhanla/SublimeTextTrans
This is nice and helpful for interim, but just to be nitpicky -- this plugin uses the Win API to set the opacity of the entire application, not just the background.
Apparently, you are right about that. Judging by the screenshot in the readme it looked like it only affects the background but after downloading and trying for myself I saw it was affecting all the windows. Still, worth being mentioned.
Enjoy
I belive it is possible to create such plugin for linux/mac but I'm not familiar with what DLL's look like in these OS.
+1 The only thing I miss from Textmate.
You know, there is this awsome "up arrow" next to the issue where you can "upvote" an issue. This makes it absolutely obsolete to post "+1" in the comments and spam my inbox when I am waiting for helpful comments on an issue.
Here, I made a small illustration: http://i.imgur.com/nCOTMAA.png
Seems like every single issue tracking system I've ever seen has led to endless +1's. The onus is probably on issue systems to do a better job of channeling human nature. Perhaps a comment beginning with "+1" could just strip out the +1 and upvote the issue - and if it's just a +1, don't post the comment at all (just upvote). Or, overhaul the comment entering system to hit people over the head with "upvote rather than '+1'".
+1, do want, will do terrible, terrible things to get
Sublime Text 3 Beta is out. Does it work now? If not, maybe we can help get it in there before release?
+1 ... just because I think it looks badass.
This would be an awesome feature.
Please, stop with +1, it only makes people get notified about your useless comment. Instead, upvote this topic by clicking on the green counter's arrow at the top.
Thanks.
PS : For windows users that want this feature, check SublimeTextTrans by vhanla and apply my fix :
https://github.com/vhanla/SublimeTextTrans/issues/2
Under any linux with Compiz, you can use Opacity, Brightness and Saturation Setting to make an application transparent.
I would dig this, especially if you had the browser underneath you could instantly watch changes...
Usually I never bother to vote any of these up and check up every so often to see if the feature has emerged.
But in this rare case, this happens to be the only feature stopping me from switching to Sublime. I currently use TextMate.
On a daily basis, I have various code windows and terminals overlapping one another. While coding, at the same time I'm monitoring what's going on in the background for activity. This is a deal breaker for me. Implement this, and consider me a user.
