After some time of just using the app for keeping track of my own games, I got myself some more motivation to work on my little game collection organizer.
With this version, I revamped the filter functionality of the program, now you can select the type of filter from a drop-down list and add filters to a set-list. These filter combinations can also be saved as pre-sets and later loaded again. These pre-sets are saved in the game collection file, so you have access to them on every computer you open the file on.
The other thing that I changed is that you can now switch from the filters to an info tab where some data of the currently selected game is shown. This is a lot better than the previous view in my opinion because you still have the game list in view.
