I also added another feature at Nils' request. IR 5.00 will save the info in both formats now. Obviously the .TXT file will not have the notes. That way you always have a traditional version of any buffer upgrades in case it is needed with other apps.
Caveat however. If you open a TXT file and issue an explicit save it will overwrite the IR file. Remember it thinks you are starting new.
So what I would do is this:
1- Start with an exisitng TXT file
2- Add any notes, changes, etc.
3- When saving IR 5.00 will automatically create .TXT and .IR
4- Henceforth only use the .IR version and let IR 5.00 take care of the saving automatically
