I agree.

It will be nice to have option smart for the existing ST2 setting:

"translate_tabs_to_spaces": [true|false]

I agree that we should be able to overwrite/disable default snippets/completions by editing only the user folder !

This is not the case for the moment I think.

You are right, if your page is not too big (and so well visible in the minimap) and If the selection color is flashy (and that is not the case in general in ST2). In my case it is almost inpossible to see the positions in the minimap. 

And if I start moving the multiple cursors (so deselect the selection) I lose the cursor positions. 

So may be I sould say : indicate the cursor positions (and not only the multiple selections).
