Every time I play ARMA, I have reason to curse the action menu.
The action menu is an incredibly powerful tool. So powerful that it has been abused by many mission/mod makers that have come to call the addAction function. This isn't really their fault, they have only less desirable alternatives to provide the player with ways to trigger these actions. BIS themselves have used it as a dumping ground for any player action that doesn't quite need its own key configuration.
Placing of explosives and interacting with vehicles/objects have the worst default implementations. 'Place {explosive}' actions have very high priority ratings, which means that they are often always at the top of the list. And if you happen to be a demo expert, you have an action for each type of explosive listed. Then, after you have placed an explosive that can be remotely detonated, the 'touch off' action appears and has an even higher priority. That's great when triggering an ambush, not so great when you accidentally place a satchel in an area that you will be spending the unforeseeable future in close proximity to.
As for interacting with objects, a lot of the problems come from plain just not using the addAction function properly. You can make action menu items only appear for a player if certain conditions are met. You can reference the player or the object carrying the action, or any other value derived from those references, as part of the conditional statement. You can make it, from positional data alone, determine if the player is looking at the correct vehicle door for the action to appear.
Even if correctly used, the action menu cannot bear the multitude of actions being thrust upon it. BIS needs to add more actions menus (radial or otherwise) and they need to make contextual sense,
i.e. A menu for each (and a separate key for each) of:
-Interacting with objects/vehicles/people (open/close, board, greet)
-Interacting with kit - non-weapon (healing myself, healing others, binoculars)
-Interacting with my kit - weapon (toggle silencer, place/remove/trigger explosive)
That alone would remove the ambiguity of the action menu and cause far less frustration.
