@treego oh, maybe I'm experiencing that too.
But because I open Whatsapp often, so I think it just happened there

why with whatsapp in sidebar? The more you open it, the smaller the panel will be

it makes me have to pull the panel again

Find Next (F3 / CTRL + G) doesn't work

this feature doesn't seem to work for me, because usually Opera always saves the keywords I usually type in the "Search pages" column.
But it has been almost 2 months now, I don't know why Opera doesn't save the keywords I previously searched for in search. when I close the tab and I reopen it then press CTRL + G,
I have to retype the keywords I want to search
