Another tactic is to make the blocking action have links to tell you which other actions should be made active. You can make a link to an action by selecting an action, doing File->Copy as Link and pasting that into the note of another action. When you click on that link, you'll get a new window focused on the destination action. If you have three experiments all waiting for the sample to come back from DNA sequencing, you could have a single action list that contains the actual work to be done on the sequencer, and each of those actions would have a link to each project's action ("Wait for sequencing of sample 035-25-XYZ"). When you complete that action to do the sequencing, you click the links and mark those waiting actions as complete, freeing the projects to go their merry ways.
