I have 2 workflow improvements:
1) Shortcut or toggle button for solo and siabling nodes. It's kinda tedious to use via the context menu.
2) I'm using VFX Console from videocopilot on a regular basis in After Effects, hence the idea. When pressing tab or between to nodes, it would be nice to have 5 or 10 customized favourite nodes right away. I guess its a little bit more work to implement it but maybe it's something worth considering for future builds.

Cheers!
