Thank you for the suggestion; kudos to Peter and Adrian for pointing out current functionality. We do have a story to improve default behavior of expressions and hairpins snapping to the same baseline. I've added your comments to FINl-4829 on the topic.

thanks to Tobias I discovered that many of my expressions were labeled under the Miscellaneous category instead under the Dynamics category (compulsory for the different tgtools to work effectively)...
It seems to me that using a 3rd party plugin to align a few dynamics is a super cumbersome way of accomplishing that task.
Any modern software would have some sort of "right click-> align" or a menu item, or something one could do just as easily (something I could assign to a keyboard shortcut, for instance). Even pieces of software that are NOT meant for typesetting or printing still have alignment methods. The fact that Finale doesn't have them (after all its years of history) is rather alarming.
So – yes, Michael, you need to (largely) improve the default behavior of placement. But before doing that, please just add a few lines of code to give a simple possibility to align dynamics manually. That's the bare minimum, in my opinion.
