In MC 9.1, I used the AW taginfo box for two types of tagging action:
* Fields that have useful dropdown menus (e.g., Genre, Composer)
* Tagging multiple tracks with the same info.
The former can now be done in MC 10 with the in-line dropdown menus, but I haven't noticed anything to make the latter simpler. Of course, it can be done (click the first track you want, shift-click the last and in the desired column, press F2), but it's a lot easier in the taginfo box. My only gripe about taginfo is that it only shows the fields I have columns for. There are in general more tags that I want access to there than there are columns that I want to see in every view. So the suggested offer of letting me choose the fields and save that configuration would be great.
But speaking of the inline editing part, am I missing something on auto-complete? In other apps (web browser url field, Excel, ...) auto-complete means that as I type characters, a/the possible completion appears after the cursor in pending-delete mode. In MC, something only happens if the menu of possible choices has dropped down, which requires clicking the mouse. Or does it? Is there a key I can type to activate it? It would be extremely nice for heavy tag editing if I could navigate the view pane entirely from the keyboard.
