Make it clearer which action a user is signing

[Soleone]

I think the actual action name is too small in the default dialog that pops up when a transaction is being created. It might also be nice to show the account name the action is being called on. If even only to clarify to new users that an action is always associated with an account, and the same action could be happening on different accounts (and do different things).

It feels like the "Actions" header and the actual name below should maybe even be swapped in size:

On the details tab its actually pretty nicely done (just could potentially clarify what is action vs account):

Right now you could even argue to merge the two tabs into one, but I assume the first might be planned to hold human readable ricardian contact info some time?
