I hadn’t seen that, as I loaded Titan almost immediately.
There are a few skins with that feature, but not as many as should have it, which is all. There should be no need to completely reset the menu to the default just to get back one item you mistakenly deleted.
Overall, the OSMC skin is definitely one of the better ones as far as clean and easy, and with decent configuration features. I’d like to see “My OSMC” items moved into a regular menu, though, so it could also be configured. It would be a good place to put a GUI config for some of the more common things that currently require using SSH. An example would be a “hardware enumeration”, which could do things like cat things in the /dev directory and output the result to the screen, so that users could verify things like HDMI negotiation.
