Seems to be an oversight in the template. I'll mention it to ProFantasy to look into.

I don't think the edit option works on lines, only on polygons.

The color is the view window color. You can change it from the View menu

Yea, I know. There is something that doesn't behave the same here as on my test server, so gallery uploads obey the same size limits as attachments. I am looking into it, but for now you'll just have to wait with the larger images.

1. It should be your local time
2. It's basically your profile page. You can put comments there, and people can respond. All your activity shows there too, like earning badges, changing profile picture and so on
3. It is for a different quote system for an older editor. Doesn't have any effect with the rich text editor, but basically, the option is how to represent nested quotes, i.e. quotes inside quotes inside quotes.

Those look absolutely stunning
