While this app is fairly simple, it does exactly what it says: provides a database for you to store tabs. With the addition of cut and paste, it is usable without your desktop. For me, this means it is actually useful. Some suggestions for improvements:
1. Better prediction of how to present readable tab. Currently te screen starts way zoomed out and always requires zooming in to read the tab.
2. Options for organizing the tabs in your database, such as by genre or with separate folders.
3. User interface tweaks. For example, having a "save" rather than "submit" button might be more intuitive. Also, if you "close" before you "submit" it should save the tab automatically, since you cant see the button unless you think to close the keyboard first.
