Customising workspace (several questions)...
I'm trying to customise my workspace to make all dialogs/tools/etc as compact as possible while still having access to everything i find useful, and running into a few issues. I've tried to find answers to these questions elsewhere, but no matter how i configure it I can't get it quite perfect. Is there any way I can do any of the following? I'll try and use correct vocabulary to avoid confusion but sorry in advance if I mess up!
In standard screen mode:
- disable un-docking of the window I'm working on. I'm aware I can disable re-docking it once it's floating, but what about the opposite? I misclick frustratingly frequently and un-dock windows while painting at the top of an image.
- hide the tab bar that shows open windows entirely (this thing:)

In standard screen mode with a maximised window: have docked tabs/toolbar visible, rather than hidden behind the open window.
In 'full screen mode with menu bar': re-enable the scroll bar while keeping everything else as is.
in any screen mode:
- dock other tabs above or below the toolbar within the same column (as in image below)

- Hide the close buttons that appear in the top right corner of floating tabs (this would solve just about everything!)
- In general anything I can do that I haven't mentioned here to get as close to this ideal interface as possible:

Please note total fullscreen mode doesn't work for me, I'm frequently without keyboard shortcuts and mapped stylus buttons are pretty precious.
Thank you very much to anyone taking the time to read this/assist!
