[Feature Request]: Save sidebar width, per tab

[JorgeR81]

Is there an existing issue for this?

• I have searched the existing issues and checked the recent builds/commits

What would your feature do ?

Each sidebar displays different contents, so each one has an optimal width for me.

For instance, I like a narrow Queue sidebar, to show more than 3 images per column.
But I want the Node Library to be wider, to show all node names, in a single line.

So, each time I change sidebar tabs, I need to change the width.

Proposed workflow

When the user manually sets the sidebar width, it will be stored, per tab.

Additional information

I added this a while back, with other sidebar improvements ( #897 )

But I'm adding it now, as a separate issue, to give it more visibility, because it's the most important one and other users have also shown interest.
