I can't seem to edit any hero cards in the slightest.

I can't add text, attributes or hero classes or even edit the card at all. There are no edit tabs, just the name of the hero, team and update button

I think @bloodwurm has taken over development. See https://github.com/bloodwurm/Legedit2.

That said, the differences between the two versions do not explain your issue. I recommend you ask in the LegEdit2 thread on boardgamegeek.com in Marvel Legendary's "Variants" forum, if you haven't already done so.

This screen is where you are meant to edit the deck's information. If you want to edit a card in particular, you are meant to double click on the wanted card in the middle panel (where you are currently seeing 4 cards (2 commons, 1 uncommon, 1 rare).

It should bring you to a screen like this one:

Hope this helps!
