Steam game indexer/launcher

Currently the current program is not very stable, it was for me the first time making an actual program with GUI, well that is not completely true, but the first GUI I made was with AutoIt and the second was with Flash, so this was completely new to me.

So now I've written this I have come to a better understanding about how I need to structure it and how the libraries work, I will probably do a complete rewrite soon to make it run better.

So to make it better I need some information:

I need to know if there is a way to gather information about the games without scraping each page individually, I have looked at the steam API, it doesn't seem like there is a way for it: http://gtm.steamproxy.vip/dev

The features I want to add in the next versions are:
-A priority list viewer inside of the GUI for both features and genres.
-Exporting all games to shortcuts in a folder structured by both features and genres.
-Hopefully a faster way of gathering information.
-Another source of information for more genres (tell me if you know a good site to scrape from).
-Better error handling.
