I don't think I've ever seen a discussion of this, or seen anything in the documentation about this, but I'm sure that everyone on the forum is aware of this.
If you create a property in your project (either in a window or class or app), you can type some text in the code editor window, and it will be saved when you save your project, and magically reappear when you open it again. This would seem to be an ideal way to add a comment about the property. Except, as I mentioned above, I've never seen anything in the documentation to suggest doing this. So, I'm wondering, since it appears to be undocumented, is it safe to put comment text in the code editor window? If it is (or isn't), how many of you take advantage of this to document your properties?
Being somewhat hard of thinking, I probably overdocument my code, because I know that a week after I write something, I'll have no idea how it works unless there are two comments for every line of source code.
