I just put the finishing touches on Default Folder X 4.6.4, which is now available on the Default Folder X page. It includes a bunch of fixes for bugs and compatibility issues.
There are corrections for problems with specific applications like OmniOutliner, Sublime Text and Reunion. More importantly, there’s new logic for automatically setting the initial folder for all Open and Save As dialogs. Seems like that’d be a simple thing, right? Unfortunately, there are a host of application- and OS-specific quirks that Default Folder X has to deal with, as well as several options that you can select in your Default Folder X preferences. The combination of all these things had made for some contorted logic, especially with Mavericks’ “creative” handling of Carbon applications. It’s now simplified and properly sorted out and works a lot better. If you still encounter problems with a specific application, send us a tech support request and I’ll have a look.
