While a spellchecker would be a nice feature, my feeling is that it must take a lot of time/energy (and possibly money) to get a well-constructed, well-functioning one (witness Indesign's miserable checker). As there's quite a bit that needs to be done to get Sigil to do the things it needs to be able to do specifically for ebooks, it does not seem like working on one would be the very best use of the developers' limited time. I understand that others may disagree, but I thought I'd give me two cents.
