Is there any way to separate our custom stack sizes from the original vanilla?

Is takes a lot of work to custom set stack sizes and the fear of having to delete or remove the data file again is really putting me off re trying the update. 2.04 appears to work just fine.

I've already made assurances that you won't need to delete the data file again. When the data file is changed, the plugin will automatically update it preserving data moving forward in version 3 and on. But there are still a few instabilities with the data file. I'll be committing a fix tonight that should fix the last of those issues.Version 2 has numerous issues, but for the most part it'll appear to "work fine". It doesn't bother me if you want to keep using that version, but keep in mind when you do run into issues my only way to help you will be to tell you to update.If you want, wait a month. Plugin will be stellar by then.

Next week I'll have support for converting the old configuration to the new configuration. You'll have to rename the old one (appending _old) and run a command, once it's implemented.
