I dont know about other people but I find myself frequently looking at the correspondence games, checking them, thinking about them and so on. But, to go from one of my boards to another i have to either click back, or home to get to the thumbnails of the boards, then click on the game i would like to look at.
My suggestion would be this… Add arrow buttons to navigate to a different board that is part of the games that a person is playing. This could be added either at the top task bar or in the collapsible menu to the right of the screen I think. Or even make it a part of the screen but not on a task bar, there is plenty of space on there to put on in, and it need not be a side arrow system but a vertical one going down the list of games, as I know not everyone has thumbnails for all the games they play.
Another addition to this would be a middle button that can go between the arrows that I am suggestion, that would offer a collapsible menu of the names of the opponents that a person is currently playing, so instead of clicking through several boards they can just go to the different names, and clicking on the name could bring a person to that game that they are playing. And in the case of playing the same person on multiple boards, a number in a bracket could determine which game to navigate to.
I dont know how valid an idea this is, but its just something I think would be handy for myself personally. I hope this is at least an interesting enough idea to consider.
Thanks for reading.
