Oh. That’s… totally a browser issue. This is not the thing I even thought could be failing, it uses the most basic way to do tooltips here (the title HTML attribute).
A full tooltip customized by Whimtale should appear when you place it into a Scenario and hover over the placed block. And what happens with the title on Chromebook is a good reason to make custom tooltips there as well.
Thanks a lot, Cosmo! I noticed this only today and it works just fine!
Also, Import NEVER showed your TileSet for me until after your v1.0.0 update!
My next project in WT is gonna be a simpler form (like Bitsy has) of your RPG Combat System, once I get it figured-out. (I'm gonna fiddle with Wareware for a bit, since Khi-R told me about it yesterday.)
