Yes
That's what the palette is for, contributed nodes covering different ideas, skills and features. So this absolutely fits. 
I have renamed the packages, now using scoped names, hopefully they will show up in the palette in the editor
@krambriw/node-red-tab-manager-v5
@krambriw/node-red-tab-manager-v4
A new version (v4 1.09 and v5 1.10) now also supporting two-way tab navigation. Missed that feature a bit and AI helped me again 
Looks updated in Node-RED flow library but not in palette manager yet (how long time does such normally take?)
@krambriw a job runs every 30 minutes to regenerate the catalogue
Ah, thank you! I just updated with new versions of the same packages and the old version number was still in the palette manager when I checked (v4 updated 2 hours ago, v5 47 mins ago))
Just a small update, my native Swedish text replaced with understandable English sentences
(Version 1.0.11 of both now available for upgrading in Palette Manager)
