[Feature]: Allow Multi Windows

[LinkeD365]

Provide an idea you would like to see in the tool?

Sometimes you need two (or more) windows, to compare things or whatever.

I can see this being easiest with 2 windows, but might be worth considering ability to dock (like VS Code) panes to give same effect within same window

@LinkeD365 Are you thinking multiple windows/instances of the toolbox, or a side by side tab view?

[LinkeD365]

probably both ;) XTB has docking, pop out and other window features, which is born from the old win style, but at least give me the ability to have 2 tools side by side, if that is easier in one frame or seperate windows, it is an improvement

I'll add side by side for now using this item and we can iterate with new items to add more abilities.
