Question Cover part of specific software in Windows 10

[DynV]

A software has a very annoying part on the left of its main window. I know if the part I don't want to see was on the right I could simply let part of the window in the virtual nether or if I had a monitor to the left I could place it on the right of that monitor so that only the annoying part was on it then turn the monitor off, but unfortunately it's not the case.

The workaround I intend to use is having a window in always-on-top mode placed right over the part I want covered. However that means that when I want to either minimize the software main window or access the software other windows, that I have to switch to the other software, turn off its always-on-top mode then get back to the software.

Perhaps you can point me to a software that would keep tracks of the window with the very annoying part and whenever it has focus that it will cover the part to hide.

Thank you kindly for your help

What is that software?
Does it have any configuration options, to change user interface and hide "annoying" part?

Seconding @SkyNetRising - what software?

However, I do not understand:

If you can slide the main window to the right and hide part of it, why can you not simply slide the left side of the main window off screen to hide that side?

Are there other windows "in the way" of doing so?

I can, for example, slide my Forum window left, right, up, down to move parts out of view.

Or simply resize (smaller) the window to make some portions dissappear.

More information needed.

Can you take a couple of screenshots and post the screenshots here via imgur (www.imgur.com)?

I'm not sure if it was an earlier subversion of Windows 10 (eg 20H1) or an earlier version but I'm glad it can do it; hopefully this thought me a bit of patience and to try it before asking.
