Looking through the forum of feature requests it seems that people have been asking for spell check for over 2 years. Why hasn't it happened yet? It can't be that difficult. I even have spell check while typing this with the browser I am using. There are plenty of PD spell check engines out there that could be incorporated.
Other than that, I love the program - just thought of another thing, right mouse click support for highlighted text - the new standard in selecting text for copy/paste/cut maybe lookup etc. And a section break in the method area maybe like the header line in ingredients so that sections of prep can be separated.
