early on in the development I decided to only use iHex to reduce the complexity of the plugin and to reduce possible misconfigurations by newbie AVR programmers (like myself).

However, if you need raw binary and/or srec formats it should be no problem for me to add these as options to the "AVR Create Flash image" and "AVR Create EEPROM image" tools.

I would hesitate to add them as separate tools as the "Tool settings" dialog is IMHO crowded enough.

What do you need the other formats for? I am asking this so can look for a solution that is best suited for your (and everyone elses) workflow.
