For those using custom ROMs and who have been flashing with HTC Sense 2.5 (aka Manila 2.5), you will surely have come across one of the major limitations of that version of TouchFLO: it can't do landscape.
The reason for that is that Manila 2.5 was built for the HTC HD2 aka 'Leo' and because that device doesn't have a physical keyboard, HTC never designed it to do landscape.
Of course the fact that Manila 2.5 was built to run on a Snapdragon CPU and the lack of landscape orientation hasn't stopped anyone from using it, namely due to all the cool new features (Footprint, Twitter tab, Shortcuts, etc.).
Luckily, XDA member Rotastrain has stepped in to finish HTC's work by releasing his 'fix', which involves Mortscript and a few other files. He's even released a Chef package to easily cook into ROMs. (So get on that Chefs!)
While not perfect, this certainly extends and fixes one of the biggest drawbacks of Manila 2.5 for many of us, so kudos to Rotastrain! Get it here.
