This developer is head & shoulders the best i've encountered over the past 2 decades in providing customer support. Makes me think of artisans who, centuries ago, did that as a matter of course - a practice that in our day has all but disappeared.
Unsurprisingly, the software reflects the developer's excellence - deceptive simplicity in form & function adapted to do what a user like me needs, (like a good poem, it masks the effort of its creation).
I'd give it more than 5 stars if it were an option.
[BTW, i'm rarely moved to comment on software, despite the fact that i buy on a regular basis, & that my decisions to buy are often meant to support developers who do good work].
