Is it possible to code some kind of separate page to delete infra? Having it so available like this with people with kids or fat fingers.
Yep, this is planned for the new design. An example for fleets is below:
“Recall” has been moved to a separate tab so that you don’t accidentally recall a fleet when you mean to attack.
Same will go for demolishing infra.
Buttons will likely also have confirmations to be sure, to prevent accidental scroll-tap situations. This will ideally be an option for those who want to turn them off.
