Pretty sure you can write whatever there, but may cause unexpected behavior with duplications (probably the last loaded template just wins). There is, but it isn't a "VisibleClass" so i understand your confusion.

when you say drag and drop the mod, how do they get the mod? Do they still need to download/extract?  I downloaded the zip, and then drageed to 0ad but I got a "failed to install mod" alert. <p class="error">ERROR: Failed to install mod C:\Users\emacz\Downloads\classical-warefare-aea-main.zip</p>

How exactly do I add bonus damage? These are the two examples I found: <Bonuses> <BonusCavMelee> <Classes>Cavalry</Classes> <Multiplier>2.5</Multiplier> </BonusCavMelee> </Bonuses> <Bonuses> <Herocide> <Classes>Hero</Classes> <Multiplier>1.2</Multiplier> </Herocide> </Bonuses> What do "BonusCavMelee" and "Herocide" refer to? Can I write here whatever? My plan is to add an attack multiplier against Ships, Siege and Structures. x And I am seeing above, there is not "structure" class?

Does anyone know where the interestinglog.html file was moved to for the R28 FlatPak? It's not in .var/app/com.play0ad.zeroad/config/0ad/logs anymore. Where was it moved to?

Indeed:
