Moving cursor through a list of files with labels is very slow

Just a comment: when i have a list of files with automatically applied labels ("newer than x days"), it gets very slow, when i move the cursor through it. When i do the same in the other file display, with no labels applied, it's much faster.

Moving the cursor through 50 files takes about 12 seconds. With the same amount of files, no labels, it takes less than 2 seconds.
