For example: I'm in Browse looking at a folder with about 500 pictures in total. It takes a good few minutes for PM+ to render the thumbnails on the contact sheet. If I leave PM+ to check my email or something, when I come back PM+ starts the rescan again. I think I've solved that by unchecking / unticking the Contact Sheet Preference 'rescan on resume'.
But.. when I leave that folder and look in another and then go back to the first folder I again have to wait for a rescan.
I can solve this by dismounting the drive where the files are located. Now my thumbnail's green circle turns yellow to say the file is off-line. PM+ now works well and fast as expected, I can move to different folders and the thumbnails appear quickly.
However, what if I want/need my files to be on-line? In fact, what's going to happen if I try to update my captions and keywords? That metadata can't be written to the files whether JPEG or XMP.
Can I have off-line performance when my originals are on-line?
Thanks!
