If I enter a search term whilst in a parent folder - I would usually expect the search to include all of the children and grandchildren folders. Eaglefiler only searches the parent and none of the subfolders.
I assume this is because a search of a whole library can be done from the root folder. However because I have all my email now in Eaglefiler searches from the root can produce enormous numbers of hits.
So I would suggest either
a) the option to search subfolders as well as the parent folder - perhaps when the folder is collapsed
b) the option to EXCLUDE some folders from individual searches.
Honestly I’m trying not to deluge you with suggestions - but within a couple of weeks I am spending a lot of my life inside of your program.
