Best Place to catch up with changes

Been gone for awhile and like the new look buuuut totally lost!

I found the keyboard shortcuts ctrl + ? some of them seem to be just icons you click on…

Where is the best place to get caught up with the changes? I like the new look I just am a little lost.

Actually found the videos…nm, seems like all the old basics still work.

You also also read the changelog, for a concurrent view of the latest major updates to RemNote, as explained here: Where is the list of updates in the latest versions? I see in my Desktop app a "Reload and Update" notice - but I am running 1.4 already - #2 by UMNiK.
