MAC724  I bought a copy and I'm very happy with this app. It does exactly what it says it will do.   
(Version 3.6.6)

MAC724  I love this app - it makes keeping track of my library very easy. However, it is too bad that the sidebar view was moved to the lower section. I think the previous layout was better ( just personal preference). Also, this second version seems much faster than the last version.

MAC724  This app is very interesting. Although it's a bit strong on the eyes (too dark), the newest version of RiftVault is a big step up from the last. Web autofilling actually makes the app useful. Also, the developer is very responsive. I sent them a few suggestions and was told they would be added in a future version. Seems like the developer wants to make this into a great app.
