not sure if this has been already covered, but when using all 4 slots of a 28X2, it would be nice to be able to , even if via a directive in slot0, be able to program all 4 slots, one after the other. i have to have pauses in the start of slot 0 to allow time to get the next slot ready and programming.
what might be the best and most configurable is a directive say "MULTISLOT that pops up the programming window with 4 check-boxes that you select which slots to program.
of course this means the names the editor has to be able to work out what all 4 files are called, so a standardized naming scheme perhaps... ok it is non trivial.
