At the moment every vehicle you buy opens up a window view of it in the depot, if I’m buying trucks or buses this could be a significant number. All the extra views kill the performance when all I probably want to do is assign a line to all and then have to delete close all the windows. I feel there’s no need to automatically open a vehicle window when you buy one – TTD did this because you had to assign the route from that window.
Same thing with the replace vehicle window, it’s not necessary – maybe just have a text popup like autosave that when clicked takes you to the vehicles list sorted by age.
I absolutely love the game but feel that you have just copied too many TTD functionalities that can be improved and streamlined. For example the depot idea is useless micro management – allow me to place a vehicle on the line and adjust the composition instantly as well as buy upgrades in situ. I know it’s not realistic but neither is trains doing a 180 degree turn in a station.
