1.- The "Release Keys" button:

• The "Release Keys" button is pretty much always shown in most residents' viewers, because many scripted attachments use keystrokes interceptions (all Franimation based AOs, for example, as well as many other scripts).
• Pressing the "Release Keys" button only results in detaching all the attachments which took control of the keys, which might confuse new users and is pretty much useless for experienced users (who will just detach any offending scripted attachment from their inventory).

The "Release Keys" button therefore takes room on the screen all the time and is hardly ever used... I think it would be a better idea to add a "Release Keys" menu entry in the Tools menu, just below the "Stop All Animations" one...

2.- The Master Remote volume control slider:

• It was introduced in voice viewers... and is pretty much useless, at least for me. Whenever I want to adjust the volume of the speakers of my computers, I use the mixer settings of its operating system, not a "Master" volume in each of the running programs. As a result, the Master volume of SL is always set to the maximum and never changed.
• The Master volume setting is also already available from the Preferences menu, making the small slider rather redundant.

The above facts are why I think it would be nice to allow users to disable (hide) the "Release Keys" button and the "Master Remote" volume slider.

The attached patch does just that, introducing two configurable settings: "HideReleaseKeys" and "HideMasterRemote", which can be set to TRUE to hide the respective items, from the "Debug Settings" panel of the "Client" menu. The patch also adds a "Release Keys" entry (below "Stop All Animations") to the Tools menu.

Enjoy !
