Maybe automatic media scanning is not such great idea after all? Do you 
plan to have this optional and perhaps have some explicit method of 
invoking it preferably even on specific directory? Most often I know 
what exactly changed on my card and would pick specific directory for 
refresh.

I think lowering metalayer-crawler priority is not a solution to the 
problem. Still you get flushed most of useful data from RAM just because 
you insert card (mostly with no change) and it takes some time anyway so 
when inserting the card and trying to play something immediatelly, you 
must wait. Also it seems to do lot of diskwrites. When rootfs is on mmc 
I can see frantic activity of mmcqd kernel deamon (doing writes?) for 
couple of minutes when booting or inserting the card (2 GB of mp3 files).

Yes, another bug :-) Would be nice to have this marvellous metadata idea 
optional. I keep my files structured and mostly I just want to play 
specific directory recursively (even with more levels). This simple (and 
maybe often used) use case seems to be not supported very well in 
current media player. The only way I found is to open one directory in 
filemanager and mark all files and select open.

I will try to search bugzilla and add this opinion somewhere when it is 
up again but I guess this could be first discussed here too since maybe 
the whole idea need some thoughts?
