1. I mini scroll bars on every table header

2. Most right column has weird fixed width. This creates empty space between the table and right side

3. I can resize left column to full width moving modified_at and labels offscreen. Then the horizonatal scroll bar appers. Ideally we want min width for each column and not allow users to move table offscreen

mini scroll bars on every table header

those are the column resizers (as you may have figured out already), but i would appreciate suggestions on how to make them look less like scrollbars

most right column has weird fixed width. This creates empty space between the table and right side

tried to fix it but it breaks resizing (causing the handle to jump when resizing starts). one question: must it take up all available space?

can make table wider than screen

intentional - this is fine with the current columns but what do we do if there are more columns? (4/5/6 columns)
see example screenshot:

although it's possible that UX may be improved, i'm not completely sure that 100% width is the way to go
