Could someone tell me: 1) Where does Lyx stores the packages in Mac, Linux, and Windows if they are different? 2) Should I do anything special to install a package beyond moving it to the right directory and do a reconfigure? 3) How can I check if a package is available or installed? 4) Are the commands of the installed new package visible to Lyx front-end and one can select them through menu bar? or should we use ERT for them?
Many thanks for your help, Artimess
