Bug report: adding custom foods is tricky

Hello there, this problem is of a lesser importance but anyway it is still unfixed at least since I've been using your awesome website for about 10 years now.

When adding custom foods the Tab key on keyboard does not work to switch to next entry.

Additionally when copying data from another window, each time it is switched to: it deselects the currently selected text entry field. So for every detail that needs to be added (like magnesium amount etc), this adds up.

Please fix this after you fix the more important localization issues?

Kind regards :)
