TLDR; Get Default Folder X 5.1.5 here. Default Folder X now shows its bezel around minimized Save dialogs and fixes crashes and compatibility problems, especially with old Carbon apps like Office 2011 and Adobe Creative Suite 6. It also addresses issues with particular shortcut key combinations and works better with Spaces.
For Those That Want Details: ‘Minimized’ Save As dialogs have been a problem for Default Folder X for some time. Because of the way macOS El Capitan and Sierra work, DFX can’t provide all of its features in a Save dialog if there’s no list of files and folders. Up until now, Default Folder X would simply not appear next to minimized Save dialogs. This caused confusion, with some people thinking that DFX wasn’t working at all, when in fact it just couldn’t do anything in that particular situation.
I kept revisiting this issue over and over again to see if I could find some sort of technical solution that’d let me get Default Folder X working in this configuration. Alas, it’s not to be – there are some fundamental limitations that prevent Default Folder X from working. So in version 5.1.5 I’ve put together a simple bezel that comes up around minimized Save dialogs and offers a single option: expanding the dialog so that Default Folder X can provide all of its features. It isn’t ideal, but it’s less confusing than just having Default Folder X missing in action when you click the minimize button in a Save dialog.
In addition to this change, Default Folder X 5.1.5 addresses a number of compatibility and stability issues (ie. bugs). I’m actually very happy to have found the source of a recurring crash that I’ve never been able to reproduce. Crash logs have been trickling in, but none of them actually pointed to the underlying problem. I’ve now found a bug that appears to be the cause of those crashes, and have also addressed bunch of other issues that have come up since the last release.
