@Lewis please test it on laptops (work with a macbook on 1280 x 800 px). Cannot scroll the overlay when I want to add a new coin.
And I cannot choose a coin. Not able to write anything in the textfield. Same with the actual site. Always need to close the overlay with ESC, then only the coin-text field stays in front. THEN I can write somthing in. Choose the coin and need to open the "add a coin" overlay again - then there is the coin inside the text field already.
So many bugs and seems all the things are not tested on lower resolutions (macbooks).
