Hello! Sorry for the delay in replying; I had to wait until the weekend to test it properly.
It finally works, thank you! I'm just having some trouble with the size of the extension window. It does not scroll, so I can't reach the bottom of it easily, not without resizing the window bit by bit a few times
I'll have more extensive testing in the future. Thank you so much for your hard work! For the early testing, it is quite impressive and exactly what I was looking for!
