I might be missing something, but is there a way to selectively delete one tempo change?
"Beat->Delete Anchor" is there for this purpose. It will change the previous anchors tempo because when the anchor is deleted the previous BPM needs to be adjusted to make all the beat lines from the previous to the next anchor (the one after the one you deleted) be in the right place. If you are deleting the last anchor the previous BPM shouldn't change but for some reason it does. I will look into it.
Also, I'm not quite clear about what the delete beat option does, does that just move all tempo changes and anchors one beat earlier?
"Beat->Delete" physically removes one beat line from the chart and readjusts the previous BPM to make all the beat lines fit evenly.
Following up with some previously-mentioned bugs, when clicking on the piano roll where no note is, the info. panel shows that note 0 (the first note) is automatically selected.
I didn't want to use -1 because that would open up some possible crashing bugs. I set it to 32767 now and it works like it should.
The auto-clap that happens once during playback has come and gone a couple times during the course of the song I'm working on, so some condition still exists where this does not occur.
The clap issue occurs when the position line is beyond the last note in the chart. I have fixed it.
If I am working on a song with a long name, I have to delete characters from the middle or beginning of the title field to verify that the text at the end is what I want it to be.
I will look into it.
Also, the field selection for all text fields in the various property windows is pretty tricky, given that the mouse Y coordinate must be within the top ~25% of the field's top-most vertical coordinate in order for the cursor to activate in that field.
I've known about this bug for a while. I'm surprised noone has mentioned it all this time. I haven't found a solution yet but I will look into it some more (Edit: I figured out the problem and it is fixed now).
