add commandline option to define order of loading plugins (or plugin-plugin dependencies)

[peschue]

to ensure that plugins are loaded before other plugins that use these plugins (like the case in MCS-IE, like will be the case with acthex)

there should at least be the possibility to specify the order of library loading on the commandline

longterm there should be a possibility for plugins to defer their loading if they depend on other plugins that have not yet been loaded (or some similar mechanism)
