Are you gonna continue your kanto tile mod in the future or is it discontinued?*(i have seen people posting pics of their updates but apparently they aren't available around, so just wanted to see if you were working on merging them)
Simple suggestion.
Add a 'Sell' option to the list when a Pokemon is left-clicked or tapped in the PC. It would pre-load the Pokemon into a 'Create Listing' window of GTL, where the user would just need to set the price and submit.
Right now, Pokemon being sold must be in your party. This can be annoying in cases where you need to sell multiple Pokemon, then refill your party.
Caves will come after outdoor tiles are complete. Indoor building tiles will come after. :)
Edit: Viridian Forest was done in this version, however there are border tile issues.
