Use an end tag to tell the plugin to check for a condition, which is written between 2 tags.
Example: for icon 10, the condition is set that it will be displayed when switch 1 is on:
Example: for a window the condition is set that it will be displayed if the variable 1 is greater than 10:
$gameVariables.value(1) > 10
You can combine several of these comments to customize different data for different conditions.
If you specify several of these settings, then the very first one that satisfies the condition will be used!
