I think transitioning to a spreadsheet at the moment is going to be the clearest and easiest mechanism to maintain while we try out other tools. Was a suggestion I made a couple of weeks ago when it was clear writing tx's into a HackMD was unnecessarily laborious and error prone.

Thanks for bumping the MMT tx log. @Dan Hassan. Pet project of mine that does work and is live, although I do think the UI isn't designed for this current concern, its an open ended system and could easily be abstracted / transitioned to another ruby/rails app to add reliability to any system.
