love the idea! i'd be willing to contribute but i'm sort of useless when it comes to go... i do have a suggestion though! lots of open source projects also use open collective [1] to crowd source funds, so if you want to add another payment method for users like me that don't have patreon that might be something to look into.
Thank you, if you want to help me out let me know :). I'll look into it, it's more along the lines of patreon/similar being a way to gauge interest and not a way to live off developing it right now.

It's golang + gtk so it uses 30MB of ram. I've made a website https://probster.com with some screenshots. I plan on making a barebones version available for download soon for all platforms, just gotta get around to it because I don't have a lot of experience with delivering desktop apps.
