Editing my watchlists

In the web version, when viewing a stock, there is no option, such as a star button, to add it to a watchlist.

Also, in the menu where I can view my watchlists, the customization options are limited. There is no easy way to move a stock between lists or assign it to multiple lists.

It would be useful to be able to easily save and organize selected stocks into personal watchlists, without these limitations.
