Camouflage. Show your desktop

Do you have way too many items on your desktop? Do you hate cleaning up that mess? Camouflage is the right utility for you. It hides all the icons and leaves nothing but the pure wallpaper.

MarcoPolo brings context-aware computing to your portable Mac computer. It allows your computer to determine its context through gathering evidence from your environment (evidence sources), using flexible rule-based fuzzy matching to make an educated guess (rules), and then performing arbitrary actions upon changing context (actions).

MarcoPolo's concept of contexts is a generalisation of a location, and encompasses more than just where your computer is. A context might represent what you are doing, or what else is going on around you.

MarcoPolo quietly stays in the status bar at the top of your screen (right-hand side of the menu bar), from where it can be configured to your own needs.

Plain Clip is a tiny Mac OS X application which will remove formatting from text which is on the clipboard. It's designed as a face­less application (i.e.: no graphical user interface, with the excep­tion of the preferences win­dow), which makes it ideal for triggering it from a hotkey / launcher applications such as Spark or Launch­Bar. For users of such tools, Plain Clip offers a way to invoke it with a shell command, which makes it possible to emulate a “Cmd-V” / “Paste” keyboard shortcut after the clipboard’s content has been converted.

Moreover, since version 2.0 Plain Clip has offered removal of trailing whitespace and control characters such as non-breaking spaces. Plain Clip 2.1 introduced another optionally text filter: line breaks can be removed, but at the same time consecutive line breaks are retained, so that paragraphs in the text are preserved. Finally, Plain Clip 2.2 added removal of consecutive spaces and version 2.3 supports conversion to 7-bit ASCII.
