We basically get requests for new features, UX improvement and other enhancements all the time.

You decided to double the asking funds on a functioning tool because a few fans asked for some quality of life, "cosmetic" improvements that wont bring a fraction of value to HIVE like the base product did for which you asked the exact same amount of funding.

extension work and the mobile App work in 2 different proposals for more clarity though.

The mobile dapp integration, maybe, if theres demand. Making tools and having no one use them is pointless.
Well if i look at it closely there will be one dapp to use it. Splinterlands with the same guys behind it like Keychain.

Call me a skeptic, but it could seem that you guys might be looking for funding from the community so you can mostly improve your own dapp because im not sure how big of a demand there really is atm otherwise..
