OK, found it and downloaded. The text it leaves in notes is:

This is not bad or too offensive in terms of corruption; it also APPENDS the Agendus ANICON# info - follows behind (below) it. So Agendus info stays on top, unlike DateBk5. Good. Attached is a zip (didn't know how to attach 3 small jpgs without posting 3 times, so rolled 'em up in a single zip which will save space here anyway).
They're screenshots of list and month views, with an IMPROVEMENT pulldown menu over Agendus - quick link to any month with a menu tap. Cool.
Problem is the icons are crowded against far left edge regardless of chosen font size. If that was brought to the right a little more, I'D PROBABLY TAKE THIS ONE AND USE IT. It has the same "blue day headers" that Agendus 5.35 used to have, which I really like. There's no "tomorrow, next Monday" stuff . . . just a banner day line. Good.
Colors are good and you can have two lines, control fonts, and show icons in month view. It does tie in with MakeSpot but I could live with that.
Next (please look at the photos) would be contact StandAlone and ask about the "icon crowding." With that fixed, and at 395k for the app and 95k for the link library, for 490k you're in business and have "most" of Agendus at a good price (think it's $19).
By the way - the icons are TINY in month view - which may mean it would take more than 4 per one-day square. That would rock, too.
