It would be awesome if you could drag/drop to reorder files and folders in the sidebar!
While I know this is often how *nix systems sort, I think many would agree that the intent of a series of numbered folders would be to sort correctly, as if they were integers.
My file layout is not particularly suited to project treatment, yet I often have dozens of files open.
Open Files in the sidebar is most useful when many files are open at once, whereas the tab bar becomes unusable.
However, finding a particular file among dozens, or scanning the list quickly to see if the file is already open is nearly impossible because the files are not in a sorted order.
Goto Anything helps, but feels sub-optimal.
Ideally, and incorporating other preferences suggested here, I'd like to be able to toggle between Sorted, Modified, Stack or Tab order.
But even a user-setting to pick my preferred order would be great.
I feel that "Files" are a bit redundant when you have tabs. What would be better is a "virtual workspace" of files/folders that aren't open. Basically have a "Group" that is a "virtual folder" that contains references to other files/folders. If the side bar looked like this (https://github.com/jezdez/textmate-missingdrawer) you could give actual folders a blue icon and groups a yellow icon.
The side bar would essentially be what's under "Folders" (with a different look). You can add physical folders to the project. When you add a "Group" they are mixed in with top-level folders with a yellow folder icon. You can drag other folders/sub-folders/files into a group and have it copy those references.
The reason behind this is "Groups" are a temporary workspace that can be easily removed (delete key deletes reference without asking). "Folders" are permanent parts of your project (delete asks you if you want to delete the actual file). With "top-level" folders you can either delete the actual folder or reference.
I know some others may actually prefer having "active files" in a side bar instead of tabs. This should be a different stackable panel.
With the tabs themselves, would be nice if they worked like Firefox's tabs (don't squish tabs too much, they fall off at some point and arrows appear, and a menu is on the right side to see all tabs).
