@Andy
No for the.openshot folder for the themes and all the important thinks (transitions, effects, themes, titles). In the .openshot it's also the xml files which are here.and it's the reason why we destroy this folder and why Jonathan asked us if we have the same problem (after a update) to keep this folder and the files and so understand why the xml file is not generated correctly.
@Diode
Yes it's the folder /usr/share/openshot/themes where you can put this theme. in using root.
In fact, all that you want to add in openshot (transitions, effects, themes, titles) is in the place /usr/share/openshot and after you put the right folder (transitions, effects, themes, tiltes) in using root. And it works fine!
Exemple with a transition .i do
sudo mv mynewtransition /usr/share/openshot/transitions/
