I like that they're doing some good UX work (although it's really just copying apple's HIG... and style), but again it's not very interesting to have a group of people working on
apps, when the apps themselves look like crap on any other desktop.
On LXQt, I made sure there was no NIH. All the apps that came out of LXQt were lightweight alternatives to bloated stuff from KDE and were "in scope" of the desktop environment. Whereas Elementary includes an Email client.
To put things in context: An email client is office software. It's such a burden to maintain that Mozilla dropped support for theirs (Thunderbird), despite its massive userbase.
People work on what they want to work I suppose, but we're talking about apps that are never going to be used outside of that one particular desktop. That one desktop out of god knows how many, since everybody is working on their own piece.
Are there really so many different ways to do a lightweight tabbed text editor with syntax highlighting in GTK, that Scratch, gedit and Leafpad all need to exist? Or can we admit there's a problem?
