I remember this conversation @jon. It would be very hard to forget as it revealed some planning slippages on our side. Currently the situation is not perfect either as we had to stop working on the Formula plugin in the PRO version and the Plugin in still in an alpha stage.
Unofficially I can say (as I think you should be informed about this) that we are going to open formulas in MIT version again. However we cannot do it before they reach stable version which can take few months. I know that it’s not a concrete information but I wouldn’t want to promise anything more than I can. I can however ensure you that you will be one of first users that I will inform about bringing it into daylight.
