Continuing the discussion from UI:
I have the same issue. Text displayed is too small for me, smaller than any other music tagging app I am using. And on top of this, the bottom text is 2 times even smaller!
I just installed Jaikoz 12.4 on Windows. My monitor is 1920x1080p, 22". Not a solution to buy a bigger monitor and don’t like to change resolution and text size on my PC just to be able to see properly what is displayed by this app. I thought my stress will come from using the app, not from the size of the displayed text in the app.
It is possible to increase a little bit the default text sizes (with 2 pix, for ex) for everything, and for the bottom text (that with Ready | n files are visible with bla bla …) to make the same size with the other text on page, please? Now, really that text at the bottom is ridiculous small. Probable I’m too old for this, or I may need to change my glases 
Hope this makes sense and something can be done.
Thank you.
