screenshot, workspace info, and text input alignment in the workspace dialog

[kswang1029]

1. if the filename is short, the screenshot is displayed nicely. But if the filename is long, the screenshot seems to align with the width of the long filename, leading to a partial display of the screenshot. We need to manually enlarge the window for a better view (and UX). Wonder if it is possible to decouple the alignment (screenshot and text) here?
   
   

2. In the above screenshot, we see the filename input field is not aligned with the upper two panels (it is narrower)
