In the current version of Orion it's quite hard to aim for specific tab or read its title on 13" MacBook. Would be great if user had an ability to set tabs height for vertical tab bar.
emvaized Can you provide any screenshots ? Not clear on what is the issue.
emvaized You really want to increase the font size? The screenshot makes this very readable so not clear how is this hard to read on your screen? Can you compare it with default font size for text?
Vlad Here's comparison with categories in Finder (set to "Middle" size in system settings)
Looking at that, tab height is the same so should not be changed but we could increase the font a bit to match.
