I wonder whether it would be worth to make sure that "OTHER" is the last item in
the list, and if so whether this should be done here or in adblockpluschrome. If
we don't explicitly handle this, "OTHER" will appear somewhere in the middle of
the list, which might appear weird/confusing in the user interface.

[Thomas Greiner, 2017/09/06 11:00:25]

Good point. We're currently not imposing any order on the items so I think we
can leave it the way it is though.

If we want to start ordering items, I agree with the change you suggested. Such
a change would be something I'd consider to be part of the UI code since it's
only relevant for how information is laid out in the UI.

What about removing the OTHER return from lib/requestBlocker and then hard
coding it into devtool-panel.html right after any, so you have any and other
appearing next to each other at the top of the list?

[Sebastian Noack, 2017/09/06 17:39:19]

I don't think the order matters much, except for OTHER, which is just weird to
have in the middle of the list. So why not just move it to the end of the list?
Well, before this change, the items were in a hard-coded order, with OTHER being
the last item. So if we agree that OTHER being last was not just coincidental,
changing this would be a UX regression.

Then requestBlocker.filterTypes would be incomplete/inconsistent which might be
confusing and likely results in bugs if we should ever use it somewhere else.
Also it doesn't seem any less code overall than just changing the order.

Yeah, I agree here. Will do.

Good point. In that case no objections from my end.
