Unfortunately there's no easy way to customize lenses, people need to write them. On the plus side they're easy for people to write, for example the Ask Ubuntu lens is about ~350 lines of code.
Please add your idea here; I'm constantly on the lookout for people to write lenses so put down some detail on what you'd like to see in the lens and maybe we'll get lucky and find someone.
You can remove the Lubuntu splash screen in several ways. If you want to change splash screens every once in a while you can run:
sudo update-alternatives --config default.plymouth
You will be presented with a screen like the following:
In this case, entering a 0 or a 1 will set the splash screen to the Kubuntu logo, while entering 2 will set it to the default Ubuntu logo.
If you want to get rid of the Lubuntu logo permanently, you can remove the package using:
sudo apt-get remove plymouth-theme-lubuntu-logo plymouth-theme-lubuntu-text
Replacing lubuntu with the desktop environment you installed.
You might be asked to remove lubuntu-desktop that's OK, as its a meta package.
If you've configured gdm using sudo dpkg-reconfigure gdm you shouldn't have a KDE (KDM) login screen. If your login screen looks something like this:
Then try configuring gdm again. If that doesn't work you can remove kdm with:
sudo apt-get remove kdm
Again, you might be asked to remove kubuntu-desktop. Its also a meta package, so go ahead and remove it.

Artemis Desktop
Formerly known as "Enjade" (read more here)
The pseudo-fork build on top of Plasma is Artemis Core. This is the project I started back in April when Unity 7 and Unity 8 was announced 'abandoned'. Everyone is more aware of Core as it has a better chance of surviving in modern technologies, like Wayland.
You may want to consider taking a look at Artemis Pure, the project's actual Unity 7 fork. Pure gets the same feature updates as Core, though it come a little later as Core is the primary focus. This is probably what you're looking for, though there is no set release yet as we are in the process of renaming files from
unitytoartemis-pure(or simplepure, for that matter). You can check this out on our GitHub repositories.Information for both of these platforms can be found on the About page.
