stedwick, any chance this will be available on the Windows platform also? I chose Evernote largely because of its multi-platform availability. I saw franzenjb's idea about using a Mac to hierarchify and then return to Windows... but unless I miss my guess, any notes thereafter created on Windows would need to be fixed again. I'm using Evernote for hours every day on each of my various platforms (presently Windows, Mac, web) and have definitely found the unintuitive non-inheritance behaviour of the tag hierarchy a bit of a roadblock. I would strongly support the features being proposed to modify the search grammar and have a UI checkbox also. Here's the primary reason I have need of it. I have the following (simplified) tag hierarchy: - next actions - projects - projects - role1 - projects - role1 - arbitraryprojectoftheweek - projects - role1 - longtermprojectthatwontgoaway - projects - role1 - newmajorproject - projects - role2 - projects - role2 - arbitrary projectoftheweek Because I have multiple roles, I would like to be able to see all the "next actions" that are in the "role1" tree but none that are in the "role2" tree. I haven't figured out how to do this easily with the UI, so I would be left with the search grammar. However, whatever tags exist in the projects tag tree are guaranteed to be mutable and fluctuating. They really are for projects that will (usually) end and so manually writing a more complex search would have to iterate through each project name in that tree (and there are actually 30+) and then I would have to update the search every time a project is added. If there is a way to do boolean logic in the UI, then that would be perfect because I appreciate being able to easily select multiple tags for the current view. Otherwise I hold out hope for automatic tag inheritance.
