So, after a bit of investigation, I've came up with this:

• Editor sidebar should be re-sizable, but the limits are between 20 and 40 percent of the full editor width. (if you can not reproduce resizing altogether, then there is also an underlying problem).
• If we're showing CombinedEditor, so the editor with docs, topology or blueprints on the right, we have that entire section be limited to 25 to 75 percent in full width, and file tree sidebar takes the percentage of that width.

Not sure if I've explained this good enough, if not, ping me for more details @anna-geller.

So, we'd need to decide here on what we want to do with the width, and would also need a wireframe from @Nico-Kestra for the search bar, on how to limit it's width.

I just think the namespace files explorer is too wide and should be small like on this screen, so I wouldn’t change the width of the search.

Hey @MilosPaunovic & @anna-geller,

You may assign it to me.

I believe this would need some more internal discussion before proceeding, but you can tackle it after, so I'll assign you for now, just don't start the actual work until we decide on the steps.

And the steps need deciding are here #7208 (comment).
So, any thoughts @Ben8t, @anna-geller or @Nico-Kestra?

Yeah Sure @MilosPaunovic

As discussed via Slack, this must be resizable and the entire sidebar incl filter are too large, let's fix it as far as we can and close

Please do let me know when I should start this.

you can go for it 🚀

Thanks for this Piyush! 🚀
