Plancoin is a "boss key" program: it allows you to hide some selected windows in one keypress.

It lets you set up two hot keys: one to hide the windows and show them back, and one to show the Plancoin Settings window. The program then runs in background and responds to the hot keys.

Plancoin Settings window

To determine which windows must be hidden, you have to set up a list of sentences. In the Include mode, every window whose title contains one of the sentences will be hidden. This mode is the default one. In the Exclude mode, every window whose title does not contain any of the sentences will be hidden.

You can also choose to mute the sound when hiding windows.

As Plancoin needs to run in the background all the time, it has been designed to use as few system resources as possible.

Plancoin was written in C++ using Microsoft Visual C++ 6.0. The installer was built with NSIS 2.23.

To keep it small and fast, only Win32 API calls were used (no MFC).

Plancoin is part of the Wistinga Projects.
