If I use the enter-button in the artists info - prompt the window will close (and save the data). Is it possible to implement this behaviour for advanced editor? There the enter-button shows no action nether close+save nor switch to the next file.
Yes, possibly although some other controls might interfere with this handling.
I will do some tests related to this to see if it behaves OK or not.
This shall be included in v 15.0.17807
