At the risk of ruffling a lot of feathers, and/or getting permanently banned from this forum... i never quite understood the session system.
If i want to sort my data by say, keeping separate analyses in separate directories, or putting masks, results, 1D files etc in separate directories, why does it have to be a hassle to use them both at once?
Why can't we just have a regular "open file" dialog when choosing overlay/underlay/Ideal files that allows me to navigate through the file system at my own leisure, instead of having to switch sessions first?
