Thanks for quick turnaround. I changed my Windows resolution to 100% and 175% and confirmed Opus is considering the DPI. I think the scaling works as expected and if I need larger fonts, I have to change font size. I still believe if Opus can persist my Zoom level on new tabs It would be much easier (comparing changing size of all fonts) so I wish you implement an option to keep the Zoom globally for all new Tabs.
Thank for help.
