Yep - some are not where I'd expect them to be either but in retrospect it's always been that way
but I suppose like a lot of us (no matter what our flavour is MS - Ubu - even OS) they all seem to have
peculiarities somewhere and we just seem to adjust and live with it or like most of us whom like to be
able to 'tinker' we change things to our own liking.
I've been doing this for years - dang it, has been that long.
Thinking about it all - I might start to get bored
and get serious with some other flavour then I
would have to start again finding out what hasn't been put somewhere I'd expect.
Still, knowing (finding out) how is always fun for me - even under KDE especially moving into the 4*.
Remember too that there (most likely) are lots of small apps installed that don't have a GUI or 'Menu'
entry and are run from the CLI and/or a Menu Entry needs to be created for ease of access.
And I do tend to agree with just19's "It is the small detail that separates the quality." though.
