NCXmms is an XMMS frontend based on ncurses. Feature highlights include its ability to control XMMS from a text environment using comfortable menu library widgets. It can also quickly find items in the playlist after the user enters part of the name. Common use scenarios are controlling XMMS remotely through SSH, or using XMMS without X11 by using Xvfb (a virtual framebuffer X server).
KeyFrog monitors the keyboard and visualizes its usage statistics. The user can obtain much information about keyboard activity: the intensity of keyboard usage, how was it distributed in time, which applications were used, etc. This may be very useful, for example, to developers to monitor their productivity. The environment being monitored is the X Window System (text applications are explicitly supported if run inside an X terminal).
That "Mature" status is sometimes not appropriate. AFAIR 1.5.6 has slowdown bug, 1.5.9 has problems with ending processes under WinME ('zombies' are staying), all versions from AFAIR 1.5.6 to 1.5.8 are having problems with ./non_existing_file under ZSH... These are the problems that i remember right now but there were more of them. Fixing bugs without making another ones is needed.
Isnt console player with equalizer more needed (i didnt find anything at this time) than player for X11? Any chances for ncurses version?
