I hope I'm just blind and not too silly to use your plugin. I can choose the snippets tab at the side panel, add/delete/edit snippets but how do I insert snippets into my text file? Drag'n'drop doesn't work and I don't know which shortcut or command to use.

You just have to type the start of the label you've chosen for your snippet and the code completion will suggest it.
And how do I add something to the code completition list?
Code completion is partially fed by latex.xml and partially computed
