I started using Peppermint 6 in September of 2015. It was a tough leap of faith to step away from Lubuntu and try something new. Having said that, I have had almost no problems. Peppermint has been excellent. That being said, I also enjoyed my Lubuntu experience.
I am always watching Youtube videos ( and sometimes making some ) of the new Linux distros for desktops and I am tempted to try something new occasionally. Currently, I am very enthusiastic about the Manjaro distros.
My biggest Peppermint gripe is that I don't know what is going on with Peppermint. The Developers are very tight-lipped about Peppermint 7. Will there even be a Peppermint 7? Lubuntu did not go LXQT as many people predicted ... will Peppermint go LXQT? Probably not. More XFCE? Maybe.
Here's a thought. Perhaps nothing will change except the Ubuntu base? Would I be happy with that? I don't know.
There seems to be no community interaction on the forums and a sort of shrug when you get a forum reply. Believe it or not I've had more enthusiasm expressed for Peppermint in Youtube comments than I have on Peppermint's own forum.
So what do I dislike about Peppermint? I don't know, that's what I dislike about Peppermint.
***UPDATE*** I heard from a Developer. I think that he wanted to start a fight. So much for a little criticism.
I'm sorry you feel we're "keeping you in the dark" Barry, so let me explain. We tend to be somewhat secretive about the next release for two reasons, by FAR the biggest of which is we don't want to say anything that could in the future be construed as a broken promise .. besides the code base, believe me NOTHING is set in stone until we're testing the RC buiild, and even then things may change if we run into insurmountable problems or spot a "better way" of acheiving something, so quite litterally there's nothing to tell, We don't set ourselves immutable targets and then work towards them, the target is constantly in flux so we try not to't give ourselves the added pressure of living up to previously stated "goals" beyond "it'll be released ONLY when we're happy with it". Secondly, sure there's a small amount of wanting a "wow factor" on release day, but that's secondary to simply not handcuffing ourselves to any particular "direction" or comitments until we're 100% sure it's the "best" way forward, which usually only gets fully nailed down quite late in the develoment process. Hope that explains things a little, but if you still feel the need to go with a distro that's more "open" about their development process, we wish you the best of luck with whichever you choose :)
I *MUST* add though, that your comment about the Peppermint "community" is IMHO WILDLY innacurate, think of us devs however you like, but if there's one thing I'm most proud of about the Peppermint project it's NOT the OS, it's the community that's grown up around it .. you won't find a friendlier, more helpful, and dedicated bunch ANYWHERE .. bar NONE.
