Useful little Add-on Rated 4 out of 5 stars

I'm now retired, so, I don't have to make that "walk down the hall" to deliver someone else's "you got a phone call" message sticky.
When I was employed professionally, this would have been very useful, and a time saver.

One thought for an enhancement -- just visual. Most people receive e-mails in graphical format (HTML). If you could tweak the add-on to send the note in graphical form resembling the input screen, it would be more attention-getting, more elegant, and would earn 5 stars from me.

HTML doesn't universally work....

...We did think exactly the same as you - having a pretty email would be nicer. Problem is that there is a significant minority of users that block HTML emails, which would make this addon less useful rather than more. We did look at dual send (HTML and Plain text versions sent at the same time) but this bloated the addon.
In the end we plumped for function rather than beauty - and beauty is in what works rather than what looks good in code.
If this drops a star for us - well, I think we'll take that on the chin and accept that it would be nice to have a prettier email - but until HTML is the only format then 4* is the best we can hope from you!
Thanks for taking the time to look at it and review anyway - even though it perhaps is not the most useful addon available to you.
