How much I missed this docking on desktop on Windows.

Being a techie, I have as everyone done millions of useless clicks and Alt+Tab just to get back to my window I was working with.

Microsoft OneNote had that feature. MS has some things that it could not treasure. AJAX back in 90s or starting 2000 was coined. MS already had that as ActiveX control in it's MSDN online library where tree node would open after lazy-loading data on-demand.

Same goes for this dock thing. This feature got limited to OneNote only. PowerToys could not deliver it.

I have it finally made for myself but presented to you all. I wanted to keep price low so that more people use it rather than less.
