Hi,
I'm requesting save / restore settings for obvious reasons : in case of a crash, having my settings saved in a zip would avoid me to some troubles to find the settings i had before reinstalling windows. Clicking restore would ask me where my .zip is.
(i do it myself actually, but that would be more noobie friendly to have a button for that ^^)
Reset settings for troubleshooting reason. If i have a random crash and i come to the forum for advice, it'd be easier to tell me : "save your settings, then reset 'em. If trouble goes away, don't restore.." than the usual "delete your abz user directory / where is it? / depends on your windows, etc...."
Reset settings could have 2 level : user data wipes config.abz, full wipes whole directory
