Former Evernote power user for years. Left because of limitations, and non-responsiveness on product dev to community requests (when they went from v3 to v5).
As a developer decided to do something about my own personal wishlist of features and build my own concept. In early development stages, but perhaps I could launch and implement features such as this. Below is a very early version product demo video. Open to feedback.
FlexRM - Flexible relational data manager.
