I try it again with other words, referring to this part of your previous 
mail:

> Completely removing the ability to be an action provider means that for each workflow transition you have, you have to also create an action, in a completely different part of the site, which "sho me" expression must match the "is possible" expression of the transition.

These are the Action specific properties currently maintained in 
DCWorkflow transactions:

     name(=title), url, category

Given more than one workflow has a transaction like 'publish': Would 
these properties be different in each workflow or would we define the 
same properties again and again?

Actions and transactions don't have to be unrelated if they are stored 
in different places. The ActionsTool could query the available workflow 
transactions and return the corresponding Actions. This way we don't 
have to define redundant permissions / guards / expressions.

If you are using the ActionIconsTool, you already have to define icon, 
title and priority in a different tool.


But changing workflow Actions would be the last step of my proposal and 
not a necessary one, so there is no need to find a consensus for now.
