When you change the layout of the old vertical style of stock data tabs to horizonal layout, some most used tabs by me are on the far right (financials and analysis). Because a horizontal row can only hold a few words before running out of room, several tabs get cut off and crammed into a "More", requiring to have one more click and choose from a dropdown menu, then choose the one I want. It's two more clicks each time.
Another issue is the financial tabs, when you open it, the cursor bar is default on the far right, in order to see all 5 columns, user has to click on the bar to move to left. It's not good at all.
