The concern was quality, too. Yes, I thought about Electron, hell I even made a prototype for that. But in the end quality counts (to me), not speed of development. I knew that I had lots of time on my hands (no investors or anything, just my own money). I didn't have anything to lose. So if you have the chance to make it perfect (versus taking some off-the-shelf tool and possibly ending up with a PDF that isn't quite what you want), would you risk it?
