"Always use normal Findbar" feature is not applied to link-only quick findbar
Title says it all. Including the latest version (2.1.8) and at least the two before that.
No it doesn't. I'm afraid it will have to remain like this for now. Links-only is a special type of find mode, the findbar treats it completely different from the normal and quick modes, like a third separate mode. To be able to use a "normal links-only" mode will depend on a whole lot of other changes I still need to do. But it is on the to-do list. :)
Something's wrong. I realized that whil using this feature pressing enter on a link doesn'T open it, so I wanted to switch back to normal mode but I can't, because it's greyed out.

You'll have to enable "Search for text when I start typing" to be able to do that. You're right though in that I really should make it so that option isn't greyed out like this.
Maybe name it normal mode or such too.
It's not really tied with the "Search for text when I start typing" feature. Actually I have that option disabled for ages and was using normal mode.
Yeah, I definitely need to change that.
