Patches

You don't want to know something about that, do you? *grin*. OK, some of them aren't really patches.

Here is a list of what I have installed as a commodity. This list doesn't contain the hidden patches in the background.

ClipHistory
This little tool by Magnus Holmgrem gives me a list of the last used clips and then I can choose one and insert it into the input stream. Quite handy that thing. It isn't a patch actually. It is system legal.
Directory Opus 5
This isn't a patch, isn't it? *g* Oh, in fact even Opus or better its task "DO_LAUNCHER" patches some system functions, at least on my system.
Executive
Executive by Petri Nordlund is a patch that installs a better scheduler - at least in my eyes - to the system. This gives me better multitasking and no CPU eating high priority task blocks out the whole system when being scheduled by Executive. It works nicely with Opus when you add the following configuration entry to its preferences:
TYPE NAME ACTION PRIORITY
TASK DO_LAUNCHER NOSCHEDULE ABOVE
Magic Menu
This great tool by Martin Korndörfer and Olaf 'Olsen' Barthel gives really nice looking pull down menus. In its newer versions 2.19 or above it behaves really stable on my system. I like the non blocking mode. When enabled the display won't be blocked when I open a pull down menu like with the original AmigaOS pull down menu routines.
MCP
This loved and hated Master Control Program of unique and very safe system patches - *grin* - works nicely with Opus when you disable all options that try to change the behaviour of Workbench. MCP can patch itself into internals of the original Workbench that aren't there in Directory Opus. It gives me the 3D look in normal gadtools gadgets as you can see in the »Commodities Handler« - CXHandler is a great Exchange replacement by Martin Stengle and B. Jessel - window. Handle MCP with care! It may interfere with Opus severely when not configured correctly.
Miami
No, this isn't a patch either. But it comes quite handy when you want FTPBatch to download some files via the great OpusFTP. Of course you can use any other Internet stack, but I prefer Miami.
MRQ
This gives me really great system requesters. It is written by Matthias Bethke. It uses the great Magic User Interface, MUI, by Stefan Stuntz.
NewIcons
Opus Magellan supports NewIcons on its own. But when you want to have AppIcons in Newicons style you better install that NewIcons patch. It doesn't harm. NewIcons is being written by the Team NewIcons: Eric Sauvageau, Phil Vedovatti, Ariel Magnum and Nicola Salmoria for older versions until 2.0.
SGrab
This great screen grabber by Stephan Rupprecht did a good job in grabbing the screenshots you can see here and in my filetypes tutorials. It sports a GUI unlike CyberGrab which I used before.
TurboSpool
Is part of the great TurboPrint printer driver system.
