EDIT:
Gregor Beyerle pointed out, that we can just save whatever template we want S1 to start with as the default Song, and then have S1 open the default at startup :) So this feature is actually more or less redundant ;)
Hiya
We get options as to what Studio One should do when it's opened... Do nothing, Open last Song/Project/Show, Open Default Song/Project/Show and Create a new Song.
Why don't we have a "Open User Template" option? I imagine it like this:
When clicked, the user can then specify which User Template S1 should open with (hence the "...")
