Very interesting feedback!
About text size: did you discover the zoom and the panning functions?
– You can zoom in and out by rolling the mouse wheel, or using the vertical bar standing on the left side of the window.
– You can pan holding the right mouse button and dragging your mouse, or using the four arrows in the top left of the window. The round button between the arrows will bring the view back to a sensible default
Changing the text size is also possible, but we encourage you to try using the zoom/panning functions. The main problem is that since you may have many tabbles visible at any time, finding a text size that fits any situation is hardly possible.
About the colours: please send me a list of categories/colours that you need, and I’ll make sure they look very bright 🙂
