I decided to take a risk and tried to publish it on Marketplace as a code plugin with links to Example Project, Integration Server and documentation. Now it’s all depends on the Marketplace team decision (as I said before, there is a high risk of being rejected). I think that widgets only will be even worse to publish because with a compiled plugin, downloaded from Epic Games Launcher you don’t need to recompile it on your own (lots of users have troubles with it), so in case of widgets-only, it would be unusable for many inexperienced users. Hope I won’t get a lot of hate about cryptocurrencies in comments in case if it will be published
