Two clicks for investing instead of one (economy, infrastructure etc.)

[Question 21]

Funny story short,

My very first moment, while going around the UI, and exploring the left vertical bar, and clicking on Economy, Infrastructure, Tax Efficiency Tabs and so on.
I accidently spent all my money on investing in random cities/provinces while exploring for example the infrastructure tab. :D
I thought myself it happens because I am new and not used to. 

Well, actually this happened several times afterwards. Because I notice I intuitively, would drag the map to see my big nation with the Left Mouse button. While tab is opened for ex. Economy Tab, I would intuitively drag the map with LMB, to choose a province, which wasn't visible on screen. But by doing so, I would accidentally invest in other province.

Could you make it so, when a Tab is opened (Economy, Infrastructure, Army, Tax Efficiency). To use LMB for exploring the map, and maybe Right Mouse Button, for investing in it. Or double Left Mouse button to invest in the province. Hence the people who are used to drag the map with Right Mouse Button, won't be in my position too xD

This suggestion is only for the map itself, not for the opened widget tab. In the widget tab, one click is more understandable for more faster way.

ALSO please add a way to invest in every city at once that you own. Or select cities to invest in with Ctrl then invest only in the selected ones. 
Would make things easier for big empires, which have a lot of provinces to micro-manage.
