Ubuntu, new programs, and opening files with them

First an observation – it should NOT be this hard to associate applications with file types in Ubuntu – there has to be a better way. And eventually these rough edges will be removed I expect. But in the meantime: Ubuntu Fix: Add Program to List of Applications in “Open With” When Right-Clicking Files in Nautilus and How do I set the default file association in Ubuntu 13.10 Nautilus/Files with Unity to something that is not listed in the Open With tab?. Re: the latter, you’ll find programs in /usr/bin/ but don’t forget to let the display load all the applications in the folder – it takes a while.
