The "Skip on demand eForms" found at the bottom of the tablet rules page is typically used for Ocean kiosks, to avoid showing the manually-queued forms, since clients often prefer to have these more detailed/private forms show on a separate tablet.
You can prioritize and apply conditions to the eForm rules in your tablet settings. Note that you can drag and drop the rules relative to each other; you can also position them in the queue relative to the "On Demand" (manually queued forms) using drag and drop.
When using eForm rules, new patients are often faced with a significant number of forms requiring completion. In cases where you don't want the patient to complete all of the forms in one sitting, you can defer automatically-queued forms to a later visit. One strategy to accomplish this is to apply a condition to the rules such that they only show when the "on demand" manual queue is of length 0. You can add this prefix to your rule's script:
ScriptUtil.queueSize() == 0 && ...
ScriptUtil.queueSize() == 0 && firstTime
--> This will only show a form once, and only if there are no manually queued On Demand forms.
