When editing in insert mode, the use of pair-matched characters like quotes, brackets, etc., behaves in non-insert mode — i.e. the matching character shifts right the text, as in normal editing, thus breaking the text alignment which one is (usually) attempting to preserve by insert mode.
This kind of defeats the whole purpose of insert mode editing, and requires manually deleting the extra characters to preseve alignment. In multi-cursor editing this can introduce even more problems.
Is this something that could be fixed globally in ST?
Ideally, it would also be nice to be able to insert-paste when pasting in insert-mode, but this might be more complicated than the above.
