The Report Dialogs are another area where mouse implementation feels primitive, and I dare say even Hackey.
This feature is a very prominent, very power interface element... but it REQUIRES keyboard input to use. How many times have I had a glass of water in my hand and been mousing around my empire to see a report come up and go "oh, lets check it out." Go down there, fumble around with left click, right click, middle click... realize I can't get where I want to go without putting my water down and say "oh never mind." I realize it's a nitpick, but little things like this add up and make the game feel clunky rather than elegant. Besides, the game is supposed to be a slower paced, more leisurely experience. Why the heck shouldn't I be able to play it with a drink in one hand? I mean I can play DoW (the most twitchy RTS there is) using only the mouse... but not SINS?!
Right now, the report dialogs require keyboard input, and they only use 2 of perhaps 7, maybe more, different inputs available from the mouse.
Here's a solution to the report dialogs that would feel more sleek, modern, and less "hacked."
Right Click on a dialog takes you there.
Double Left Click on a dialog takes you there too... because people double click on things expecting it to do something.
Single left click on dialog will select the dialog box, at which point you can use the mouse wheel to scroll up and down the the recent event list. While selected, you may right click the dialog box to go to the event, or left click it again to deselect. (this does not have to interfere with your current unit selection)
Left-Clicking and Right-Clicking to scroll through a list?! It just feels so crude, especially when my mousewheel is sitting right there. The only justification I can think of for avoiding the mousewheel is because left and right click is easier to program... there's a word for these kinds of decisions.
I love the game, but I am beginning to lose patience for these, what I percieve to be, less than thoughtful interface decisions that fail to take into account standard software interaction conventions.
EDIT: I don't mean to be a jerk about such things. Ironclad and Stardock have done such a great job designing new interface innovations that seeing them drop the ball on such rudimentary things like effective mouse implementation really chaps my hide. And the fact that I know you're listening makes me even more prone to speak my mind and tell you what I really think. Thanks for listening.

Do you think the mod tools will be capable of implementing some of these things?
