Hello @yshulhevich ,
Thanks for letting me know that it's not working in the schematic editor. That is definitely a bug and I'll report it once I can reproduce it.
For the deletion issue, I'm assuming the layer is empty since that's a requirement for the deletion to work. I'll explore that and try to duplicate it as well.
According to the documentation GROUP ALL will select everything subject to the selection filter. It's possible that at one point it only worked on visible layers but as of right now the documentation doesn't reflect that and rather ties selection to the selection filter.
Thank you for posting these, I'll investigate these and make the appropriate bug reports.
Let me know if there's anything else I can do for you.
Best Regards,
