We agree and we are currently testing different ways to implement this, without causing UI/UX issues. One approach we favour currently is to have a switch in a users account settings to set a "global" denominator that will affect all price UIs.

You should give the option to send tips with SAT denomination too, not only with USD, as it is in Fountain for example. I should be able to send a tip to somebody with a preset amount of sats just by pressing the like button, just like in fountain.
