How can you hide RAW files from thumbs?

[obelisk]

thumbs + filename view

There's no way to hide raws at all

Even if you put nef cr2 raw pef and uncheck every box in custom filter, it will show.
I don't think that include/exclude row works properly.

Also if I change the custom filter in the options, the settings don't save so next time I open it'll be the same as before.

you need to use Filter by>custom
