"My Portfolio" - Summary Tab
After playing around with the new layout for several hours/days, the only main issue regarding layout is the Summary tab when clicking on individual portfolios. That is way too number-focussed for a "summary page" and it hurts to look at.
If you could just take out half those figures (avg. daily volumes, high/lows, open/close) on that tab, then you could make space for the headlines/articles section on the right half of the screen, sort of like before. That would largely solve it for me.
You corrected the issue when clicking a link/reference within articles. It not opens a new window again. Well done!
