“Show only selected handles” Plugin doesn't work

Scripting

I installed the plugin “Show only selected handles”, but it doesn’t work.
Even if I turn this feature on, the handle will still be showed.
I tried this in Glyphs2 and Glyphs3 trial.
Do you have any solutions?

It probably needs an update because it hasn’t been used much.

You may need to deactivate the default display of handles: View > Show Nodes > In Foreground (Cmd-Shift-N). I’ll see if I can autodisable it when the plug-in is on.

I was able to use the feature by deactivate the default display of handles.
Thank you so much!

If you colud update this plug-in, could you show handles while controlling the curve like the following example?

I don’t think that’s possible in the current API.
