A new version of Zeeedit was released on Jan 1st 2013. PC only.
People may well quibble about the license terms (42 euro locked to one computer), however I think it is an excellent investment if you intend to get serious use from the FS1r.
Sakura is also excellent, but Zeeedit wins on presentation – everything is laid-out beautifully in comprehensive overviews. This makes the FS1r very accessible to me. YMMV.
I decided to record my largely incoherent ramblings on Zeeedit – doing so provides an overview of the FS1r architecture. This will bore the hell out of 99.99999999% of people. But I think it might be be useful to the new FS1r owner struggling in the waves. Hence, and for posterity…
No loud noises in these ones…
