Hi Ale

and.. c for count, p for pointer, a for apples, i for image, p for picture, si for selected items..
or whatever.

Using something other than i,j,k is not better or worse. This is really pedantic, and there can be
very good reasons for using something other than i (like when counting apples and a might make more
sense? :)). Don't forget, some of the code still has its German heritage in place too.

I don't see any massive value in an effort to rename them in one go, but feel free to using i,j,k in
your own code. If you or others want to work to rename things, then cool. Having a generalised
convention can be of use which I would support, but enforcing it is not entirely a good use of time
or effort.

Thanks
