I find the flight plan activate button too pegged to the flight plan. I was actually looking for it for a good minute before "finding it".
Maybe a small space/division between the flight plan and activate button could be placed.
Ok... I think the problem is formatting of the classic theme, as both Light and Dark theme display this correctly with a space between the flight plan and activate button.
The classic theme is a compromise, and a bad one at that. Might do another round of "small fixes" some day, but that has no priority at this point in time and I'm swamped with other stuff.
While I know classic theme is a compromise, I have a feeling the majority will be using the classic theme, and it will be something like 60/30/10 split among classic/dark/light, or maybe 60/35/5. I think that classic theme will be kept by most current users (cannot say so for newcomers). You can run a poll later on (let's say one week after the introduction of 6.2 to all game worlds) to see which game is the most popular. But maybe you at AS can even query databases and see the number of classic themes in use? It could be an interesting and revealing data for you. And if you can not find it out that way, you can always broadcast message in all game worlds inviting users to participate in an online poll... I am a marketing guy, so I could design the whole response campaign for you :) with all the bells and whistles such as incentives etc. Anyway, what I want to say is that information is power, and you can easily find out what the users prefer by using data mining techniques, either through internal databases or by user participation. Such information may prove to be invaluable to AS.
