There's a feature called Crop and Lock, which lets you crop a window to a selected rectangle that's then pinned above other windows.
By detaching the rack window and cropping it, you can effectively create a VST-style floating window for a rack device. Hitting the close button restores the full rack window. Instructions:
- Install Microsoft PowerToys https://aka.ms/getPowertoys
- Enable the "Crop and Lock" module
- Detach the rack and press Windows-Control-Shift-R. Use the crosshairs to crop out the desired portion of the rack.
- Close the cropped window when you want to restore the full rack.
- Right-clicking does not work within the cropped window.
- Occasionally, the cropped rectangle is slightly off and needs to be scrolled or re-cropped. Cropping also won't work properly if the rack window is full screen prior to cropping.
