Two Suggestions for Increased Functionality (put all that consumed RAM to use!)
1. List the Folder location of the file without opening Finder.
I have organized my files coherently; location provides contextual meaning as important as the search content. For example, I glean clues from the Folder location, because of how I have organized such as date, client name, etc. These context clues are missing from DSE results entirely and similarly looking files returned from a quick search would be aided by the additional visual clues from Location --> which could be a toggled option.
2. Search of OpenMeta Tags
If you have meticulously tagged your files with Tagger or TagIt or some similar app, DevonSphere Express won’t find your tags! This should be a simple matter for your talented developers to address and hopefully they will.
