Guild Wars Build Manager that is worth a mention: GW Teddy
I am currently in the process of creating my own application to help manage my guild wars skill templates, when I came across this application: GW Teddy, you can find it here: http://gwteddy.manuthie.de/?menu=home&lang=en
It certainly has all the aspects of what I was hoping to acheive in my guild wars build manager, however the most useful features I am looking for are not there.
Such as searching folders recursively for a specific build, or automatic organisation of the skills, or backup mechanisms for saving the templates.
Still, a very good app worth mentioning.
