Hi,
These are both excellent suggestions. The tab one I won't implement right way, but I'll definitely add it to my list of suggestions. The look-cursor distance I can add as a configurable setting for the next version. I'll try to work on it later today. I always credit people who make suggestions that get implemented - I can credit you as Stevie-3, or something else if you prefer. If you don't want to post it here, you can just shoot me an email. My address is on the website.
Thanks for the suggestions!
