GUI best practice:


When the user selects an object, a dedicated GUI space should be reserved that is not blocking vital click-areas


However, when the user triggers mouse-over functionality, it is fine for a tooltip to block areas, as the user just needs to move the mouse to make the tooltip vanish.



ES2 suffers from a tooltip-scissor effect, where your mouse pointer might be pointing at an anomaly on the right hand side of the screen, but the tooltip is opened at the left lower corner. 


This leads to a scissor effect, where you either can focus your input device (mouse cursor) or the information, but never both. Depending on screen size, the user must even move the head.


Also, the functionality appears inconsistent, as some "small" tooltips appear right next to the text, while the "big" tooltips appear in the corner. (Check planet anomalies for example).


From an ergonomical perspective this behavior is far from optimal. 


Therefore I would suggest to add the option (and make it default) to have tooltips appear next to the mouse cursor. 


There might be cases where this does not work well, and thus this would be needed to be evaluated on a case by case basis.
