Creating your own Actions - Action Design Guidelines
Since many actions are used with each other in Action(s), they should have a consistent look and feel. Probably the most important piece of advice is to keep an action as simple and as discrete as possible. An action should not attempt to do too much. An action that resembles a multi-tool will be too specialized to be useful and will limit the user. If the functionality that you want to provide is complicated, consider breaking it up into many small independent actions.The user interface should also be kept as simple as possible. You should try to minimize the use of vertical space. In particular, use combo list instead of radio buttons and avoid tab views. Probably the best strategy to adopt is to look at the other actions in Action(s). The more you can make yours look like the ones that are already there, the better off your users will be.
