I have made a series of changes for gyro based remotes to make them easier to use.
I made a small demo video here:http://www.youtube.com/watch?v=L067P7Stass
Particularly, if you are using a gyration go mouse, or a wiimote, there is no easy way to toggle play/pause, or a mute. My latest set of changes fixes this.
This was implemented by using the various "FS Options" screens that were un-used in UI2, but are used in UI1 when you tap on the screen using a remote.
Due to the fact that dan.g made the FS options screens using the standard variation, and there is no copy/paste in designer, I had to completely re-create the options screens, manually making sure to create the new designobjs for the old UI1 on the Normal Horizontal 3:4 variation.
Once this was done, I could make my custom UI2 screens, making sure to add goto screen commands in the original FS screen to go to the new screen, making sure to set both timeout and screentype values for the designobj as appropriate (MythTV needs the screentype set appropriately, so the system knows its a full screen navigation screentype and button presses will go to the right places etc, even when on my custom screen)
I hope this makes things better to use for everyone, and shows a bit more of what Orbiter can do.
