Privacy Browser Android

It's not a big difficulty btw. I frequently started changing user agents due to browser incompatibility, disabling dark webview due to some missing css sections or fonts, etc.

I noticed that accessing page inside menu, felt pretty much repetitive.

If there is a way to implement holding the current tab in tabbar to assign any function, is that possible to assign page section to it ?

It's just a UX improvement. Nothing huge.

I personally find that if I am doing much with the user agent I almost always create a Domain Settings. Are you saying that you are often changing the user agent for web pages you only visit once or otherwise aren't creating a Domain Settings for?

I often changing UA, not for a specific website, but for different ones. Like reading different news articles. Hence do not wish to create domain settings for them.

Same goes with dark webview mode. Although I feel like turning into light mode completely in the future, as many websites look broken with the inversion of background & foreground. I'm still using it for the hope that I can access disabling it frequently with ease.

Not specifically moving it into the tabbar hold. You can keep it in menu as it is & assign the menu list as a shortcut for tabbar holding.
After holding the current tab, just spawn the page menu list, which'll help access the temporary toggles must faster.

I'm not even sure if there is a programatic way to open a subpage of the options menu. Everything can be accomplished by adding enough custom code, but I generally like to stick with standard Android tools unless there is a compelling reason to do something different.

I think you should close this in favour of #1145 because I'm expecting current tab hold to spawn history dialog.
