(Note, if "Real-time indexing" worked as advertised, I wouldn't need this feature, but RTI seems to cause program trouble at best, and I've not seen it actually do what's expected in any case.)
Often after juggling files around, I'd like to have X1 reindex one or more specific folders (including its subdirectories) right away so that I can browse around in the new file structure using X1 to see whether I need to do any more shuffling/tweaking/cleaning etc.
Right now my only option is to kick off a full reindex of everything on my computer, which can take up to an hour, just to have X1 "notice" the few folders that I want freshly reindexed.
It would be really, really handy if there was a way to tell X1 to immediately run off and refresh its index of just the folder(s) I ask it to scan. It would still keep the index of "everything else", of course, and still reindex the whole bloody computer at the next full reindex operation.
