IsVisibleFor0Entries
IsVisibleFor0Entries specifies whether a plugin is visible for 0 selected entries. It is set to FALSE by default.

e.g. In case you want to show the PluginCmBbMte plugin while selecting nothing, you can set IsVisibleFor0Entries to TRUE.

Worth noting is that this parameter only works with plugin allowing to be visible when 0 entries are selected. If that's the case, then this parameter has no effect, and the plugin will not be visible anyways.
Possible values: TRUE,FALSE
Default value: FALSE
