My idea is that we should be able to spend the money we make on itch on other games without having to withdraw it. This is already implemented in Roblox where developers earn robux, which they can either cash out or spend on other games. This system saves Roblox a lot of money long-term as small developers who doesn't make substantial money worthy of cashing out simply spend their robux on in-game items etc. I think that this would be very nice feature for small developers who just want to make games and spend their earnings on other games.

 This would also eliminate the issue of double taxations due to multi-country transactions and also the issue of commission fees taken by online banking providers.

TL;DR: We should be able to buy games with money earned from selling our own games without having to cash out.
