A: I have tested the addon with 2.83 and higher versions. If you have a problem with any of those versions, please let me know.

For 2.93 use at least the version (v 1.1.1).
For 3.0 use at least the version(v 1.2.0). This is compatible with all versions sice 2.83 and above.

If you have a problem with any of those versions, please let me know.

A: Yes, you can swap as many editors as you like. 
For example: From A to B, from B to C, from C to A. 
This way you will have a carrousel that will go through A, B, C sequentially. 

A: Of course. You can do this in the addon preferences preferences.

A: Yes, you can disable it in the user preferences. Additionally, you can also assign another aspect to it, if you don't like the one that comes by default.
