I just switched to Tixati. This is a really stupid question but how do I change the order of downloads. I have 4 downloads running. 1 is in queue. The 4 downloads that are running have 0 seeds, so I want to download the 1 in queue. I tried drag and drop that didn't work.

Stop then restart one of the running and it will become the queued one . Once downloading you can drag them up and down. You can also choose settings then under transfers choose general and increase the number of downloads you are allowing.

simply open more download slots

thanks

You can click drag any downloading transfer to QUEUE and it will be in line after the current queue.
Also SETTINGS -> as mentioned (Turn off recycle slots to keep X down and Y upload, but keep on auto-manage 'queue')
If a transfer is downloading, then set to seeding (turn off all files) then turn files back on it will go to top of queue.
