Group creation is not work

[newillusion]

Thanks for good instrument!

I can't create a group of any mind nodes, keyboard keys are not work and menu item is gray.

Is it a planned behavior? But whay? Hierarchical map structure is mach-mach more useful, then flat. For example, film scenary must contains several act nodes on top level, then every act must be devided into scenes and so on. With flat structure easy operation possible only with small count of nodes ...

This was not planned, I will look into adding Group support for the next release.
It is one of a few bugs that I would like to fix, thanks for posting the issue!
I will update and close when I have a fix ready for release, but it will not be for a few weeks, at least.
Thanks!
