I was outside for a walk and I had this Idea:
this is a program which load all mintSoftware like mint-/tastymenu or mintInstall.
mintPluginEnvironment is work as a control program which supervised all mintSoftware for bugs and unknown access. If you found a bug in one of your Software you can first patch the Environment and than you have enough time to Fix the Problem in your mintSoftware. Also mintPluginEnvironment detect a recourses-hungry-monster like python if mintMenu updated by Synaptic.
Also control mintPluginEnvironment mintRecue for backuping files and so on.
Look at my picture:
as an exsample for a mintInstall file opened by firefox.
