I think it would be great to have an option which allows indexing of folders on different schedules. For example, if you have a folder with lots of static data, don't index it with the same schedule as everything else (after all, that content will not change, but X1 could potentially use millions of CPU cycles to make that determination).
In my case, one of my hard-drives has about 300,000 files (most are saved html pages, take less than 10K, and never change) and indexing it takes about 30 minutes overall. With folder-by-folder scheduling, I am sure I could tweak it down to about 3 minutes or less. That would be awesome!
Well, there's my two cents anyway. Keep up the good work!
