Hi Jani,

Welcome to Subsurface!

I started programming a couple of years after you did, but still, it's been quite a while.
Subsurface really needs more Mac / iOS developers (we actually have a couple now, but still, way too few).
There are, however, a few things that are rather unusual about our setup

(1) the code is all in C/C++, not in ObjC.
(2) we tend to have decisions driven by our ability to do things consistently across all our supported platforms (Windows/Mac/Linux/Android/iOS) 

(3) because of that we use a fairly unusual UI library (in the Mac/iOS context): Qt and QML - that will likely involve some getting used to
(4) this is open source with no hidden financial tricks, no ads, no nothing - as a result we sometimes make choices that are driven by making it easier for ourselves, the developers

It should - but it's also possible that there's something broken there - iOS is the platform with by far the fewest users (and active developers)

Yes, see (4) above... I maintain the cloud server, so if people have problems, I can tackle them from the server side. Supporting the "native" cloud environment on each of the platforms plus the "industry standard" ones like Dropbox, Box, OwnCloud, etc would drive up the support burden for us quite a bit

I'm on a plane right now (and will be for another few hours - I left Spain this morning, actually) - but I'm looking forward to your contributions... please look at the files for useful information about that. One of them is the requirement to sign off on your commits (I just got the email from derek that points that out)

> I have to look closer at the config file, because I avoided adding it to my LibreOffice setup (it is stored in a second file, which are not kept in git, so nobody accidentally commit their developer id).

Always interested in advice how to make things better.
