[GUI] Need to resize or enlarge the `List Certificates` windows and columns

[The-Lum]

Hi @kaikramer, @jgrateron, and all,

• Could it possible to resize or enlarge the List Certificates windows?
  • Version of KSE: 5.5.2

Observed during testing #377:

• Is it possible to resize (on the max.) this windows?
• and (especially) the columns? It is currently not possible.

See screenshot here (with red arrows):

In fact, the main question will be:

• What would be the minimum acceptable size (of the List Certificates windows)? depending or not on the contents of the table according to the preferences of the user...

Thanks a lot. Regards, Th.
