I don't mean just hiding it from view, but completely disabling it? Think RSSOwl's "List" layout where the internal browser is no longer used.
Unfortunately, now is not so much time to make such an option, it is necessary to rewrite a lot.
It's not really that big of a deal and QuiteRSS is great as-is, I just figured that since I don't use the internal browser I could maybe get a performance boost by disabling it completely.
Thanks for the answer though, and for the awesome software.
