Hi Elizabeth,
You're right, on both counts. :)
However, if your Firefox window is maximized, it takes an unnecessarily large screenshot. And although using Firefox w/Notable's plugin is a useful workaround, Safari is still my preferred browser. As you might imagine, I'd rather not have to open Firefox every time I want to use Notable without problems!
The bug with Japanese font rendering in the regular URL Capture feature really should get fixed, as it's not such good form to rely on users installing a plugin for a specific browser. And don't forget about mobile users!
Alternatively, if fixing regular URL capture is really that big of a problem, would you guys please look into preparing a Safari Extension? It looks like they're quite easy to make, and it would undoubtably bring you more customers. You can get more info here:

Best regards,
