Names can settle a numbering question
A split release, special or different season grouping can make two menus look inconsistent. Compare the actual chapter name and date instead of treating the number alone as a complete identity. Noxx links an episode back to its series and displays the surrounding season so that you can recognize where it belongs.
Save the last chapter you finished
On the series page, choose the season and enter the last completed episode. The form checks that the number exists in the recorded season. Save it as a manual reminder. It does not monitor viewing elsewhere or set an exact playback timestamp.
Return without reading ahead
Episode titles can reveal story information. Open only the season you need and use the direct search result when you already know the chapter. A checkpoint is useful precisely because it can reduce the amount of searching and reading required before you continue.
