Spreadsheets for cues, intensity palettes, focus palettes, color palettes, and beam palettes should all be tabs. So when I press the "plus" icon in the tab bar of any frame, it should give me the option to add a tab for a cue spreadsheet, an intensity palette spreadsheet, a focus palette spreadsheet, a color palettes spreadshet, or a beam palette spreadsheet. I want to be able to view my spreadsheets in live or blind. I also want to be able to view more than one type of spreadsheet at the same time. As it is, if I open a blind spreadsheet and set it to one type of record target, it changes all the other open spreadsheets to be that same record target, which is unnecessary and doesn't help me.
