Am I missing something? I can't find "reader mode" anywhere in the settings. Looked in the "webpage" section of the settings with no luck. I am running the latest snapshot. I, also shut down my laptop each day.
For now you can enable the readability filter (< > sign on the left of the zoom slider)
A proper readability button is coming (soon I believe)
Got it! Thanks!
In the status bar, at the bottom right of a page, is a pair of carets facing left and right. Hover this, the tootltip says "page actions." Open that, and about 2/3 of the way down the list of actions is "readability." You can activate that for whatever tab you are on. There is no global reader mode, nor is there a persistent reader mode, AS YET. It's a much-requested feature, and sure to be added at some point. In the meantime, that page action is what we have.
I also figured out the page zoom thing. See https://vivaldi.net/en-US/forum/vivaldi-browser/15150-page-zoom-resolved
