I have just downloaded and compared the UECIDE display of UECIDE-0.8.8alpha22 and UECIDE-0.8.9-pre9
The only thing left that is quite small to read is the bottom output window or "Console".
all the menu item are readable the plugin manager is all readable.
In the attached screen capture. On the left is Pre-9 with scale set to 200
on the right is the alph22 with font set to 24.
As you can see on the left all the text is readable except the bottom portion, it is still the current version.
with the text scaling factor set to 200%, the text size is the same as having 12 pitch on a regular monitor.
so the text at the bottom black area is about a 6 pitch in my screen very hard to read.
