hmm my thoughts now!
First, off topic, /me likes the middleclick == new tab
Then on topic, the ability to enable/disable them and to choose which colors are used for hidden/system files is a MUST. Especially since, as mentionned before, we can already choose all other colors (including filters) it really wouldn't make sense otherwise (and would only confuse people

)
As to keep it or not, I guess you should keep it. I might use the system filter, hidden I don't need it (the icon is enough for me

) But might be useful for some, especially since it's been requested

I think it should go to the actual color filter list though, especially since it would allow one to use the ordering of that list to define which filter overwrites which (for both hidden and system files, or hidden and any other color filter).
Maybe add two items (Hidden & System) that either can't be deleted (delete would reset them to default color instead, with a message maybe to inform that they cannot be deleted) or add under "New" add "New Attr." for an attribute filter!
You might also get readu for some people asking "why only thoose attributes? why not read-only too??"

So you could e.g. text-color a whole drive including all branches in the tree by simply defining a filter "E:\*" plus some color. Or certain sub-branches... similar to boxed branch, only forecolor.
Would be slightly notable in tree display speed, though, I guess...
Well, I don't think such an expansion would bother me (aka i dont really care

), but I do beleive it should not be extended to the tree.
Thoose new attribute filters should behave like current color filters do, so they should be LIST filters. The tree already has its colors (box, highlight, etc) and it might get messy to add (part of) the color filters there.
Ok, it means hidden folders are only recognizable through their icons, and system ones not at all, but that's only in the tree. They would get color filtered on the list (as color filters behave now) so would be allright by me.
(system folders could get some red cross/symbol as overlay maybe if really needed maybe...)
@RalphM: Go in Configuration/Colors and check Apply color filters to get them working on the list aswell
