Privacy Browser Android

Hi, Thanks for your good browser.
I tried many browsers on android, Only this one is the most handy one I like most.
But to my daily usage, It lacks some Font Size options like other browsers,
Which are: 33% / 67% / 80% / 90% / 110%
Can you please add these 5 Font Size options?
BTW, If you think there are too many, Please do add 80% / 90% / 110%
These 3 options is really necessary on 10.1 inch tablet devices.
When Font Size is set to 'M' in android display settings, the 80% / 90% makes the text smaller and easier to read. (Won't be too large)
And When I choose Font Size to 'S' in android display settings, the 125% makes font too large. So, I really wish to have Font Size 110% options in this case.

Thanks for your great work.
