How can I change gui font size? Is it really simple app or useless trash?

I'm talking about that left column which has so small font, so it is hardly to read for me. And i can't see logic in your app. You say that it is simple? So your app doesn't have preferences? but it has dev tools!!!! What????? Is it simplicity? Some list of options is normal for simple apps, such as font size(not only in editor) etc. But chrome-like dev tools is something really illogical. I'm going to write text in "Left" and I want to see normal gui but I have some useless dev tools(as for me, simple user) and can't adjust appearance of the app as I want.......

Also, guide says "Highlight some text and press... Read Moode". But how can I highlight text? It doesn't work! I used mouse, Shift+arrows, Ctrl+A. Nothing helps. Can you create video for super stupid people as I, how use Read Mood feature. Or, maybe, problem isn't in me.....))))

You can decrease font size using ctrl - and increase it with ctrl +. Them it's ctrl 0 to reset it. The shortcuts are listed under "view" in the navigation bar.
Highlighting text should work with shift+arrows, or if you select with your mouse then press ctrl k. I'm not certain why you're struggling to highlight text, which OS are you using? What happens when you're trying to highlight it? Do you see a change in colour over the selected text?
