fix it > reporting it > doing nothing
Right?
No, but there are over 180 bug reports on the bug tracker right now. That means it might take a while until a developer finds some time to fix it (especially if the bug is not game breaking).
And considering the time it takes to create a detailed bugreport, it might be even faster to fix it at once instead...
So the final solution is to open a SF-acc and put each of those in one separate bugreport??
No. Again I'm misunderstood
Standard procedure: Report your bug on the sourceforge bug tracker (title, for example:[map] subway: several minor mapping issues)
The sourceforge bug tracker has one problem though: It will only accept attachments <=256kb, so attaching multiple screenshots there is quite a pain - In this case you can also open a thread here, if you like, and link from the bugreport on sourceforge to the screenshots posted here...
You are limited to 4 screenshots and 1024kB here (per post).
