Currently, it appears that collaboration is limited to locking the entire document. Is it possible that will change? It's pretty inefficient in this format and would be better to at least allow simultaneous editing of different scenes, locking only the scene currently being accessed by an author.
Liking the application so far. Hoping also to see the following suggestions implemented:
1) as mentioned above, scene-based locking for collaboration vice document-level locking.
2) CELTX native format import.
3) Audio/Radio-play format.
