Currently the player allows displaying either the release rate or the spawn interval, spawn interval is saved internally into the editor's output, but the editor requires release rate. This means that players who use spawn interval have to convert to release rate when using the editor, or manually modify the spawn interval in the output file.
The editor clearly already knows how to interpret spawn interval, since it's what gets saved into the file. Would it be possible to allow users to use spawn intervals as well if desired?
