**Please see the asterisk below for another useful idea I've floated around but haven't gotten much traction with:
I think the colony jump click would be helpful. I usually don't cycle HQ's constantly. I've never really thought about doing so. I will have to play a game and see how it impacts the experience. Having the number keys jump to a particular HQ is a very good idea though.
I usually tend to my own HQ and respond to price signals reactively. I'm still somewhat new so I haven't developed a proactive approach of monitoring other HQs yet.
*Shipment path click-to-jump:
The other idea I have is more complicated, but I feel players would really find it useful. I know I would.
Would it ever be possible to click on a shipment path and jump directly to the associated building? I find myself having to zoom out so I can quickly scroll toward a distant elemental quarry or metal mine and hold 'X' to see the revenue (I have to zoom back in to actually see the revenue sometimes - running 720p on an old machine). This is the only technique I've found to make sure I'm not running unprofitable harvesters. I always find myself zooming back out and scrolling to return to the HQ. I guess I could press '1' to cut some time off the process, but a jump-click to the shipment path's associated building would be very useful to reduce the time on the front end of the procedure. (I realize there are many auto-off options for unprofitable harvesters, but I haven't explored them yet. I'm addressing the part of actually getting to the building though.)
I realize implementing this functionality would be difficult near the HQ where all the paths converge, but would be feasible and very useful if you were to enable it outside a certain radius from the HQ. Maybe even put a (colored?) indicator on the lane indicating the point past which clicking will jump to the associated building.
As a corollary maybe you could click the lane again after having jumped to jump back to HQ. Just another thought.
I also realize you would have the problem of lanes that criss-cross and other player's lanes to deal with and it might get far too complex but it's worth considering.
Maybe run it past Soren.
