That's a new version of FileSieve done and released. I think this particular version has the biggest change log so far. It would've been bigger - he said - but I, for some reason, decided to revisit the Script plugin.
I don't think I've gone into this before other than with a small forum post, but I started a new (Method) plugin a while ago that is what amounts to a small programming environment.
The purpose of the Script plugin is to allow the user to program their own Method and Modifier plugins. Full intellisense, code completion, debugging, and all that guff. It's undoubtedly far too much effort for the outcome of only a few people even being able to effectively use it as it requires programming knowledge. And then the documentation. Holy crap - no, I've already been through that nightmare with the original VoiceMate Professional.
While working on the prescanning threads feature, for no explicable reason I decided to jump into the Script plugin and work on that. The plugin all now builds and runs, but then common sense won out in the end and I unloaded the project from the solution and ended it there.
As for the prescan threading: it didn't make it into 4.20. The scanning was never designed from the beginning with concurrency and so random things aren't thread-safe, resulting in Weird Things Happening. I'm not going to delay the new big release because of this, so the threading features were disabled and the new release has been made.
