🐛 [BUG] - Shrink/resize the tools window at the maximum to just fit the content of the toolbar

[lobre]

Description

When I only show the "tools window" and try to resize it to the minimum possible width, it does not go as far as just fitting the toolbar content.

You see here there is horizontal blank space while if you take a tool such as Pinta, it will naturally shrink to fit the content.

Expected result

It shrinks horizontally to fit the content of the toolbar.

Actual result

There is a gap on the right and the toolbar cannot be resized more.

Steps to reproduce

1. Click on the "Windows" menu and deselect everything except "Tools".
2. Grab the resize handle for the "Tools" window, and shrink it at the maximum to the left.

This is not a big issue and there might be reasons. I guess there is a hard-coded minimum width for other potentially larger widgets. But for people who like minimalist interfaces, it would be a nice addition to be able to shrink to fit the content.

I realize the same happens if I try to position the toolbar horizontally at the top.

@lobre Hi Lobric Thank you for your report! Indeed this has been an issue for a long time. From what I know it seems to stem from how the Qt Framework widgets work.

@MrStevns since you have worked on the UI recently and we briefly discussed the toolbox widget "width" in the past, when you're available could you perhaps provide a bit more insight in order to understand this issue better? Thanks in advance!
