Visual Slickedit has a cool feature where the mouse can select a block of text as a rectangle within the screen rather than across lines of text.  For example:

   a quick text example of where something
   might be a block select rather than a text line

   select

if we used a block select on the first two characters in the above text, we'd have 3 lines:

   ['a ',

    'mi',

    'se']

This can be very useful for inserting text, filling in comments, cutting text, etc.

Is possible or am I bypassing sublime commercial license?

I would love to be able to select which characters commit the autocomplete -- for example, dots & semicolons. When in an object-oriented language, eg, the dot is often the next desired character. The dot-autocomplete would save a keystroke.

Reproduce: Take a Sublime 2 window drag to any secondary monitor. Take another Sublime 2 window drag to same or different secondary monitor. Heck even select a Sublime 2 window in the primary monitor. Try to drag any of these to the first Sublime 2 window. Drop taget is never activated to add to the tab bar.
