Would require a rather extensive rewrite and expansion of the config file access function. I agree it would be a nice touch. Memory is getting pretty low though, specially with the older devices. Will keep it in mind.
With regards to other suggestions made, one was automatic saving of config files: gave this some thought, one problem is that this would disrupt the display for a second or two while saving, so if done often enough on a time basis to be effective, could become annoying as well as result in lost data. Likewise if done after menu changes: It would have to be continually saving configs after changing settings to be effective enough to save the last configuration. Otherwise, when would you have the config save itself?
As far as a past suggestion to change the shortcuts, I’m reluctant to do this. I suspect most users are by now familiar with the operation as it is, changing things would likely lead to frustration.
