What does cutter means? I think it is a basic function that supposed to be enabled when MMU is present right?

Hello.

RGB status bar: https://help.prusa3d.com/article/status-led-explained-mk4-xl_418975

Input shaper: https://help.prusa3d.com/article/input-shaper-mk4-xl-mini-_451816

Touch Sig workaround: https://help.prusa3d.com/article/touch-screen-mk4-mk3-9-mk3-5-xl_689554

As for 'Set Ready'... this function allows you to upload multiple print jobs to the printer via Connect. After you finish the first print and prepare your printer for another job, you just click 'Set Ready,' and it automatically starts the next print job.

Some of the items of the menu are clear, titles are self explaining, but for many others I need further explanations.
As an example RGB Status Bar, Set ready, Input shaper, Touch Sig workaround.
Is there any site with the information I need?

Enabling 'touch' is missing from the above documentation.
