3. You cannot DELETE a multi preset completely. I made a multi preset "TEST" to check some things and when I tried to delete it, this "TEST" name was still there. Also, there was program #0 in the slot 1, so it was not empty. Also those earlier "- EMPTY -" presets were like that (program #0 in first slot). If I remember right, those empty multis were really empty in v1.3? In other words, all the slots were empty. For me this is an important feature, there are cases when I want Origin to be silent and it's usefull to have really empty multis.
This "empty multi" which is not really empty is present in the firmware since the beginning (ie 1.0). So it was also the case with the 1.3.50 firmware.
I went back to 1.3 and I noticed that deleting works like that in 1.3 too, so I remembered wrong. But still this minor bug was there in 1.4: deleting multi does not delete its name! This should be corrected too.
I am glad to hear that we'll have a new version soon.
As said earlier, my first update try went badly in mac. Update process got stuck (and lost a connection) and also crashed Origin connection app. Gladly I have pc too, but this is not the case with everybody...
