Hello and sorry for my long break.
I have not forgot your reports and this tool.
Also i want to thank jcnossen for uploading a library. 
It should still be compatible with the Arduino IDE 1.0.
Not sure about the libraries though.
So i updated it and it is now possible to install or remove multiple libraries at once.
Download Ardulibrary 0.1.5
//Edit: fixed now some bugs in version 0.1.5 and i fixed the updating. now as soon as some new version of a lib is published and "install" is pressed, the old version is deinstalled with the old file-structure and the new version is installed.
