IntelliJad 0.5 just got released into the depot.
Key changes are...
1. The memory file system is now the fallback decompilation FS - this reduces the number of cases in which decompilation fails due to configurational issues
2. If you try to decompile without the path to the Jad executable defined, you have the opportunity to cancel the decompilation or open the config and correct the issue. *
3. Reformatting styles are now user-preferred OR debuggable.
4. Local file system decompilation is now based on the memory decompilation to provide greater control over file content.
Thanks for all the comments and suggestions so far!
