And in respect to the action:
If you only use 1 particular action all the time, then Actions button opens the dialog and - if you have ticked only that action in the long list of actions - that action will be executed when you hit enter or click OK.
Web sources: the last used web source is remembered so you only have to click the web source button in the toolbar again.
Yeah, im referring to removing tag data types, i.e. remove id3 v1, ape etc. not fields
This doesnt strecth the cover, it maintains aspect ratio. it's more of an OCD thing, but sometimes it can just be a couple of pixels out on one dimension when down-sampling.
Correct, but my suggestion is to add a specific action group to the tool bar
Correct, but I would like to be able to choose, for example, cover only itunes US, UK or tags as well. Depends. Would be much quicker (for me) to be a button I've assigned on the toolbar to which i can just use muscle memory.
