Since the newest build is out and this feature is still lacking, I'm going to bump this thread up again.
Brad, I don't know what you use to code BeerSmith (VB, Visual C++, whatever), but imagine if every time you wanted to save your code, you also had to close the project. You're not done working on the project, you don't want to close it, you just want to save the code you've written so you don't lose your changes, then you want to continue working on it. You'd get pretty annoyed if every time you saved your code, it also closed the project on you and then you had to go reopen it.
Saving without closing is a standard feature of almost every good computer program that allows saves.
Please implement this in BeerSmith.
