hEgelia: "Anyway, most if not all, 'Select' functionality we can clearly distinguish from RISC OS 5 are actually manifestations or surface extensions of quite deep rooted OS enhancements, going all the way to the core of the OS. What this means in practice, is that porting over our favourite Select / Adjust stuff to RISC OS 5 is practically impossible, since it would also involve altering or rewriting some core RISC OS 5 elements."
Totally, utterly and absolutely wrong!
RISC OS is one of the most extensive operating systems ever written, every single API call can be replaced or enhanced via the software vectors and the relocatable module system. I have been through the Select change logs with a fine tooth comb and there are no *features* (as opposed to reorganisational changes) which can't be implemented as OS extensions. It is entirely possible to do this and leave the core of RISC OS 5 containing the HAL and hardware drivers in place (which it would be pointless and counter productive to try to reimplement, just for the sake of it).
Indeed this is precisely what ROL have quietly demonstrated on the Iyonix for the best part of 2 years, but have either lacked the programming resources or will to get in to a releasable state.
