Hello! I know you can press INSERT to insert a new node between selected segments. Trouble is that I don't have an insert key and under keyboard preferences, this isn't an option to change. Looking online, I found out that I may have to do some minor coding to achieve this... Is there any easier way...

Ahhh there it is! Thanks so much!

After rectangle selecting, the transformation gizmo does not appear after selecting a single node, with the toolbar button selected or not.

I'll play with it and see if I can get it to show up, thanks for putting me on the right track!

the "display handles bounding box at the node tool's toolbar" is the one that looks like four arrows pointing outwards? I've tried selecting and deselecting various buttons at the top but can't seem to be able to select multiple handles...

If I select a node and want to scale both handles proportionately, I know I can do Shift+> or Shift+<.

Can I achieve the same result with the mouse? Moving/Scaling the handles simultaneously and proportionately?
Thanks!
