When site links are saved on Speed Dial they get assigned their colour. It would be preferable if I could choose the colour - often colours automatically chosen are completely dissimilar from site colour theme. It makes it harder to navigate quickly - I have to read each tile description. Also sometimes tiles change their colour, which again makes it harder to navigate quickly even if I remembered previous tile colour.
Is it already possible to make tile of some defined colour and not it let change colours?
I remember before sites got saved as small screenshot of the site or something, but not anymore...

This is not very important, but there are 2 things that really bug me. If anybody from Opera browser for Windows PC development (or anybody) would change them I would be really grateful.

1. This small arrow pointing up/down and sideways which appears on videos and gifs and opens a smaller video or gif copy when pressed. It often hid text of videos I watch so I really wanted to turn it off. I found something about going to opera:flags#media-detachable-view to disable it, and it works. Still, please remove it! At least remove it from default settings. A way to turn it off was too hard to find. And I still don't understand what it was for, besides annoying me and probably plenty of other users.
2. When I save a link on Speed dial it is automatically assigned a colour. Very often the colour does not fit site theme, and it gets harder to find site among other tiles. I would appreciate an option to manually change colour of a tile.

That said I really appreciate all hard work Opera development team have put it this product. Thank you.
