This program is one of the most important developments that LaunchBox has ever had. This one program sets LaunchBox (even further) apart than any other front end. The ability to create themes simply with a GUI is just amazing. y2guru has worked tirelessly on this project for at least 4 years. I have followed his youtube videos and it's clear that he's cared about the little things. With 2.5 (releasing very soon) the wheels are visible when creating a theme and this makes a giant difference in the ease of creation. This project is a one of kind labor of love.

Ive had the week off of work and this has been a lot of fun for me during my time off. I haven't begun to understand everything in it but it makes creating a theme possible for someone like me who has no experience with coding.

This is such a great tool for this community. Thank you so much for making this. I am absolutely loving it. Once I got it figured out and working I was able to build an entire theme with in a few days. No way I could or would have without this tool. 

Please keep this going, I am looking forward to each update and the future of this project.

I finally got around to giving this a try. Wow!! What a wonderful piece of software. I am no coder, and I was able to stumble my way through it pretty well. I ended up starting with the Tilt theme as a base, and started tweaking it to my liking. After a day of messing around, I now have my own custom theme, that I (kind of) created. So cool. Thanks to the dev so much for creating this. I can now  make my own refinements of themes, instead of begging the original authors to do it for me. Win-Win for everyone 😃

Looking to create a theme for BigBox?

This is what you should be using, whether you know XAML or not.

This is just an amazing program.

Great stuff! As a beta tester for Community Theme Creator, I can honestly say it's a huge gift to the LaunchBox community and to the aspiring theme creators out there who don't want to mess around with programming code. It's fairly simple to use with a lot of useful features while creating themes that can be added to BigBox.

Great app, just need to include a pasue, star, etc mode to edit that, this can be incredible if you add it!!! thnx

Link to review


Note: If you get a load of errors after inputting your name and hitting next, as reported by WolfRamiO You need to run BigBox at least once, which if you have no games added will entail running LaumchBox to add at least one game, then running LaunchBox. Easy to get caught out if running against a clean/new install of LaunchBox.
