Not had a chance to look through the whole posts here yet to see if this has been mentioned sorry but there seems to be one tiny bug I noticed with it.
It would split everything perfectly except for the first split would keep the start of the item on it as well.
So if you did a recording of say the words "1, 2, 3 ,4" but left a few seconds at the start of the audio file and then used the below settings
-"Split selected items"
-"When gate opens"
-"when gate closes"
It would nicely top and tail the words "2, 3 and 4" but the word "1" would be cut correctly on the right side but the left side would be the start of the audio file rather than the start of the word "1"
Hope that makes sense!
