Feature Suggest: Allow shrink/expand grid

[eval-exec]

This extension is great.
When I opened a tab which title is very long, I can't see it title in Tag-Manager-Plus's tab view.

So, I suggest to allow expand/resize the width of tab grid, then we can see wider tab title. :-D

Thank you.

Quick access to a select column amount function might be a good idea.
