Enharmonic notes are pretty simple to understand. There's a reason why I refer to the lowest note on the left side of my instrument as a D# and the note at the top right as an E flat. It has to do with the context of their location in relation to the tuning scheme of the hammered dulcimer.
I think it's a good idea to acknowledge the enharmonics all over our instruments. You never know when a G flat might show up in your music, and knowing it is enharmonic to F# (leading tone to G) helps. :-)
