Windows App Recommendations?

Hi!!!!!!!! 

I'm really into decorating and making my PC even cuter with Windows Apps for customization. I already downloaded Rainmeter, RetroBar, and Open-Shell for my NSO themed computer. It looks awesome with all the skins, but I just got a 16 GB RAM upgrade, and I want to use MORE memory!

I added MusicBee to add more cool stuff to my computer and I love it! It's a way better music app than iTunes is! Does anyone have any more recommendations? It could be for anything really. Customization, radio, art, IDK. I just really want to take my PC to the next level and get more use out of my computer! 

I want to be able to play or do anything to make it fun and cute! 

Thanks in advance! <33333333
