I wanted to like this application very much, but could not.
A hefty download at 20Mb with Marble, after installation it runs as an impressive memory and processor hog.
It's interface is badly laggy, which impacts negatively on it's ability to be used intuitively.
Fonts are way too small, and buttons lack suitable visual feedback.
Desired information stored in the app seems very difficult and frustrating for the user to acquire.
Marble Maps v1.0.0 is very rough and much in need of improvement and optimisation.
