Ok, thanks for the votes.
On the capo item, I often add the bpm count as an item in the 'box' of the lower part of the metronome, which works quite nicely, and I imagine something similar for the transpose icons. I would also like non-zero to be a bit more 'stand out', if I'm honest.
That metronome tweak came about because several times I had been asked "what speed is that", which is now much easier to answer. Happily, bpm is available as a field
Recordings. It's not so much a reminder to pick a different one, rather an indicator that one intended for Duo backing is available for this song. So if a recording exists with "Duo" in the title, my proposed highlighted/reversed text would appear, to indicate that. The chances of me remembering all the songs which do and don't, correctly, are quite small, while singing, playing, stamping on FX pedals, mixing and remembering to smile.
The number of attached recordings, which we discussed once before would be nice, on the Recordings & Documents icons too, as discussed. This of course ceases to be useful if I go down the road of brief, silent recordings in order to maintain the, perhaps 3, 'standard' number of recordings attached. As I suggested, that thought is rather a work in progress.
Keyboard player. He's from the Musicals and cruise ships world, and uses sheet music for a number of our songs. If he/we get around to loading those into BH, then some songs will have his documents attached; and some will not. A recent bass-player also had the dots for a few songs. I'm wanting an obvious indication that there are more than the usual 1 Lyrics document attached to a song. Or are you going to tell me that a default Document of "2" would display a second one if it exists and normal Lyrics if not? I just thought of that.
