Shouldn't we move the refactoring branch to next first and only move it master when at least all core functions are ported? master is used by quiet a huge amount of people after all... > > I will be really happy to start working on the refactoring branch. > However I don't know how we can coordinate the work between us > since some core parts are changed.

Additionally we could set up a list with tasks and ideas. Would mantis be appropriate for this? Btw. I started working on (and hopefully will have time to finish this week) adding clips to the timeline, this affects Bin and Timeline, UI + Model. greetings, Till > > regards jb > > -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlEtBEgACgkQzwEyz7QP6nSFMgCgwAGfPMal6EcHJn9QrKkF2DQg J+wAn0OxkYAJjwegtZlV2vw8HFie8eUc =o56C -----END PGP SIGNATURE-----
