Why is the Dashboard so very limited for the number of tabs or quick links?

It appears that I can only enter up to 12 ‘favourite links’ on the dashboard. Any more and they disappear with the necessity to change the view with a small tab or dot. I frequently access about 30 websites and I have grown used to having them all accessible quickly from one new tab page. I can of course use a new tab extension but I find the dashboard page very good and it is disappointing that you do not allow the user to customise it more broadly to include many more links. Please would you consider an option to have more columns and rows on the dashboard on which I can display frequent or favourite links.
