My current project is reminding me of some small annoyances when tagging (not new to .493)...
I seem to have a lot of CDs that aren't in YADB, so eventually I'm told "No tag information for the CD in drive D: was found. Do you still want to rip this CD?" Answers are Yes or No. This dialog would be more helpful if it also offered a link to type in the CD and tracks information before ripping. As it is now, I either must say Yes, end up with a list of Unknowns (including inappropriate cover art), then go back and fix them all, without the helpful Disc Information edit form. OR I say No, then navigate to the CD drive letter to again open the tracks, edit the information, then rip. Lots of extra clicks either way.
Another stumbling block is the default size of the tags panel, when I open if after ending up with a list of Unknown.. tags that need editing. If I want to use it to type in the tags info, I open the tag panel and usually it shows just the first few fields of the view. It is NOT the Default Tags panel, it's the Tags in Current View panel but with odd behavior -- no scrolling by it or me. Even if I start typing in the first field, this panel does not scroll or resize by itself. Worse for me, I usually want to start with the Album name, and in my view that's a few fields down, just out-of-sight, but I can't get there. If I put the cursor in a visible field and tab down, I move to the out-of-sight fields but I can't see them. Only when the tabbing gets to a field that has a picklist (Keywords) does the panel switch to showing me all the fields in the view, resized and/or with scroll bars. It sometimes works as desired, Tags in Current View in a larger panel with scroll bars, but quite often that panel format is NOT triggered and I get stuck with the fixed size tags panel and no scrolling.
To avoid the tags panel size problem, I usually try to edit tags directly in the view. But either my aim has worsened, or MC has gotten more particular about recognizing which view column I want to edit. I think it used to reliably use the column and row under the cursor when I press F2, but recently it's tended to open some other column, sometimes one I didn't last-edit in the view. I've looked for a pattern of what tag it is remembering, and why, but don't yet have a theory.
