@gave92 Thank you for using CsWin32! This is our short term goal, which is to use source generator everywhere.

I've added a setting under Experimental to enable/disable the feature (default: off). The feature may be good enough for first release :)

I had some notes on this but I'll have another look since it's been a while.

The main point to figure out before merging is whether the terminal is global, or if there can be a separate terminal for each tab & pane. I lean towards the second option (similar to VS Code).

Holding off while @hez2010 checks if it's possible to use Windows Terminal control.

Added ability to have more than one terminal 😇

Switching between terminals is working nicely!
