Order of focus changes #83
Description
Freecol is turn based game. And in every turn one should move units (that are not town population).
However when number of units grows, I find that the order of focus changes (please give me better word) is not logical and seems random.
Let me give you an example: suppose there are 2 colonies or clusters in different part of the (new) world with ships, wagons and units. Now when I have moved some unit, and would want to move other unit visible on the screen, instead the focus jumps to other location 2, where similar there may be 2-3-4-5 and more units that needs some of coordinated movement.
But instead after (spending some time to reassess and) moving one unit, the focus jumps back to location 1 or worse to location 2 etc...
I would like that the game would bring first focus to next unit visible on the screen (preferably first from those close to each other in the screen center). That would give workflow for each turn, when starting from say north part of east cost, then moving slowly along the cost to south, then some remoter locations.
(The observation, that in all games the most and largest colonies happen on east cost)
The problem and the solution proposed are for game in later stage.
The problem significant in a way, that I find uninteresting to open previous games as with larger number of units it become more boring experience with every turn. For me it is usually 20+ colonies, 100 units in say 1560 with military still far from enough for independence war and trade with Europe being still profitable.
