Sometimes a set of pages just needs a different data-saving setting.
Changing data-saving setting currently requires 5 presses to change, plus 5 to change back, plus you have to remember to do it.
How about something like one or more of the following:
<> change data setting for n minutes
<> reload this page with data-saving off (one time)
<> reload this page with [no|high|extreme] data-saving (one time)
<> change data setting for this tab only (persists until this tab closed, spawned tabs [inherit|don't inherit] setting)
<> change data setting for this domain ([persists|resets] on restart)
(plus similar options for requesting desktop version of a page or site)
Opera mini is great, I recommend it to everyone.
Thankyou for the best mobile browser!
