ViewFinder and Zap
Zap is a popular text editor for RISC OS. Thanks to collaboration between Zap maintainer Darren Salt and Windfall Engineering, Zap can make use of a hardware accelerated string drawing routine that vastly speeds up bitmap font drawing (if you use outline fonts, you won't notice any difference).
How to combine all the downloadables from the Zap website can be a complicated matter, since there are, well, many. Hopefully someday they'll make things easier, but right now you'll have to make do with a number of beta and 'test' releases of various parts of Zap.
Go here for details about how to harness Zap's support for ViewFinder.
ViewFinder and ArtWorks
ArtWorks is a popular vector graphics editor for RISC OS. There are several incompatibilities between ViewFinder and ArtWorks. Thanks to Martin Würthner several of these problems were fixed by patching ArtWorks.

ViewFinder, Acorn UniBoot 0.67 and RISC OS 3.70
Acorn UniBoot 0.67 is a 'universal' boot sequence for Risc PCs running RISC OS 3.x. It is available here. There is a problem running UniBoot 0.67 under RISC OS 3.70. Due to the way UniBoot patches the RISC OS 3.70 ROM, ViewFinder will malfunction. A fix is available.
Download the patch here.
