- You want the information easily noticeable, rather than relying on you to click something to check view state.
- You want something your whole team can use, so you can share the responsibility.

- Counts VIEWSTATE Length
- Calculates a PERCENTAGE

- v2.0 Migrated from Manifest V2 to Manifest V3

Simply reads the size of the first __Viewstate hidden form field. If you are using viewstate chunking this is worthless.

Je weet meteen hoeveel procent van je pagina uit ViewState bestaat. Snel en simpel!

כל כך פשוט, קל ונח.

Needed to refresh initially to get information to show, after that worked well. Requires access to full page which is guess is unavoidable.
