Re Enhancement idea 1: Yup, your understanding is correct. Pressing 'space' while you are typing the tag will include the space inside the tag, for e.g if you type 'advertisement ' and search, there will be no return results. If you type 'advertisement' exact and search, there will be plenty. Right now I'm still allowing space as a part of the search tag.. But this is an interesting aspect you brought up, I will keep in mind.
Re: Enhancement idea 2: You mean the 'Add adver' text? That's because you typed 'adver'. Whenever you type something, the text 'Add something' will come up as per what you typed, you can press enter to select whatever you typed as tag.
You can click on the 'x' sign to delete individual selected tags.
And also, the search bar doesn't allow for duplicate tags. If you have already selected one 'advertisement' tag and try to input another exact 'advertisement' tag, it doesn't allow.
Thanks for the resteem ;)
