Wow TaggingMode, I've finally found it :-) These functions really need to to me in the Tools menu as well!
Now I've I've tested it, it seems really useful and it's pretty intuitive. Thanks to the reliable undo/redo, it's pretty safe to have a play around without really screwing this up.
A couple of initial reactions;
- Checkboxes imply that more than one option in a scheme can be selected. From what I can see, this isn't possible (I've only tried with Artist and Album, but I'm guessing that's the case). The fact that it's a 'tick' helps slightly, but it's still unintuitive by not following windows standard. Other options would perhaps be bolding the selected option, or putting a border around it, or using more Radio Button (option buttons) type design.
- This was a little off-putting; I was messing around with tagging mode with the album Keep It Unreal, by Mr Scruff, with the panes 'Artist' and 'Album'. It's the only Mr Scruff album I've got. I changed the artist to Black Sabbath. Mr Scruff then dissapeared from the panes list. I think it would be a lot more friendly if it had stayed in the list.
