Hello!
Me again...

I'm making little comand plugin, and it is almost done, but...
I need to store edge selection to use inside plugin, and i used a edges selection tag well, but discovered that generation of that tag makes separate undo group. And if i store selection with a tag, i need undo several times to undo my plugin.

Is there another way to store that selection?
Thank you!
