I don't know how many Evernote users there are on these forums, but if you haven't tried it, Evernote is a very useful data organization and management set of tools, but whatever you do
AVOID EVERNOTE 6.0 that is currently on the App Store. For many, perhaps most, Mac users Evernote 6.0 is unusable. Old notes get lost or take several
minutes to display, edits do not stick, new notes simply disappear, and the UI does a great job of inducing eyestrain.
Version 6.0.1 was released by Evernote that corrected at least some of the functional errors followed closely by 6.0.2 that correct most of the remaining functional issues and at least makes the UI readable, even if it still induces eyestrain. Unfortunately the App Store approval process takes time and Evernote 6.0 is the only version available at this point in time.
If you use Evernote, either download 6.0.2
directly from Evernote or wait until the 6.0.2 version makes it to the App Store.
