Apologies if this has been suggested before. It's kind of hard to search for.
Really wish there were an option to delay the start of changes on each monitor.
For example, I'd like to be able to set all to change every thirty minutes, but set the second to delay changing for 15 minutes. That would mean one is changing every fifteen minutes, but not both at the same time. Makes for a much better slide show when the computers are idle.
I have three computers set up with five monitors. This option added would make for a much more interesting display.
