In my last post I wrote about the Orion Browser, which is capable of running addons like Mudcat Browser Tools (MBT) on iPhones and iPads. Here is a comparison between Orion Browser with MBT and the default Safari browser on my small iPhone SE.
On the index page the lines are too small to read in both browsers so I have to 'reverse pinch' zoom in. But MBT moves the 'number of posts' column to the left so that it doesn't disappear off the screen when I do.
On the thread page, MBT increases the font size of the post compared with the rest of the page so I can read it without zooming. In Safari, I have to zoom which makes the lines go off the right hand side. (Or I could turn the phone sideways.)
As I mentioned, you have to configure the display layout and font size changes in MBT - they are off by default.
