Committing to any new google products is just asking to be disappointment.
There is no culture of keeping and improving any product anymore, if there ever was.

Using local currencies is good for the economies themselves, as it gives them autonomy.
However, These governments can weaponize their own currencies too.
So using a 3rd party stable currency to assure value over time and that neither party could manipulate the value makes sense.

Also, a lot of economies carrying a stake in each others currency will make going to war more costly (for everyone), meaning that it might serve as a stabilizing factor. I cannot imagine the Yuan replacing the dollar, as China will not hesitate to weaponize it if it suits them.

Those first 2 are definitely good enhancements.

That’s a mighty leap.

It is a shame, i liked the app a lot.

Lemmy is on version 0.18, the main focus of development will be core functionality. Now more Developers are getting involved stuff like this will pick up for sure, but the system as a whole is a work in progress. In the mean time you could discuss the types of modifications you like and even add enhancement suggestions to the appropriate Github, and if you have the development skills, get involved yourself.
