Well, I found a great resource for additional free modules!! (They do have a link to make donations, if you feel so led.)
Take a look at Bible Support for a whole plethora of study tools and modules… Specifically, I was searching for the Yonatan and Onkelos Targumim, and they have both, now in my ‘library’ in my e-sword!! Membership on the site is required, but it is quick, free and painless.
They have the base e-sword as well as most anything you could want… More reading than I’ll accomplish in the next few years! Again, for a preloaded Hebrew roots specific e-sword, go here.
