I had to take my epub over into Sigil since the editor doesn't have a spellcheck yet.

The implementation of spellcheck in Sigil is pretty good, but it does have an aggravating flaw.

Sometimes it suggests a word, fine. But I want the letter in front of it capitalized. I fix it, when I tell it to save, it changes it back to a small letter again.

Per se, it is not a calibre problem, but it is possible you may use the same libraries and so on in implementing it. The point is, I would ask that it be possible to turn off suggestions, so that this sort of thing can't happen in the calibre editor's spellcheck whenever it becomes available.
