Where in the original You have shutter speed control?... AFAIK camera-ui2 (now camera-ui) implements all options from original + indeed many enhancements, that are do-able from GUI.

fCam drivers are totally different topic and while I *do* like them very much, there is no place for them in camera-ui replacement. We *don't* want do-it-all hybride here, that will fail due to over-specific-dependant-chain. You know old linux mantra - write programs that do one thing at once, but do it best. While it's not *literally* true nowadays, it stil got rationale - why to create behemot, when anyone interested can write useful, independent program using fCam drivers, and anyone interested can use it (or not, therefore is not forced to install fCam drivers with CSSU, which would not be the case if camera-ui start implement fCam dependencies).

Anyway, it's quite academic talk, cause I'm pretty sure Nicolai don't even consider rewriting camera-ui to *such* degree. Hopefully... (fixme if I'm wrong).
