There is currently one flag for Hoedowns -- (P) Patter and two flags, I think, for Singing calls -- (S) Singing and (A) Sing along.
Then there is one for Rounds (R) and one for Line Dances (L).
I would like to be able to sort the tunes by "effect". For me, that would be something like "Rousers - Patter and Singing", Cruisers - both P and S, and possible a couple of others as spares. I was thinking that perhaps they could be labelled in the program as S1, S2, S3, P1, P2, P3 etc. which would enable each caller to subdivide his records according to his own ideas.
To add a flag,
Note that the letter corresponding to the flag must be unique, so that, in the above case, if you added Rouser (R), then you'd have to give Rounds (R) a different letter.
Then, for your 'Patter Rouser' records, mark both the 'P' and the 'R' flags. For 'Singing Cruiers', mark both the 'S' and the 'C' flags.
You could also add a flag for seasonal or holiday records such as Christmas, Halloween, St. Patricks Days etc.
Other users add flags for categories such as 'Gospel', 'Rock', 'Country', 'Patriotic', etc.
