This is a very nice design and I approve heartily. This means when I go on a new skill set spree with several skills training levels I and II early on, I don't have to muck with skill switching between home activities and lunch breaks. Instead I'll set them up in the 24 hour queue and have the last skill to start be something long until I can come back to it. Very nice.
The skill training system we came up with allows you to queue skills that will start training in the next 24 hours. You can enter in up to 50 skills in a queue, as long as they all start training within 24 hours. This leaves room to start a skill that will take 6 hours, followed with one that takes 12 to complete. With only 18 hours of training prepared, the queue still has room to start another skill.
If you train a skill the old fashioned way (by activating a skill as you do now without the queue window) it will still be listed in the queue as the top skill; the skill you are training now. If you don´t add a follow-up skill then you´d have to come back when that skill is finished. You can still start training skills from your normal character sheet without entering the queue.
Apocrypha just looks better and better from over here.
