Zotero trick: priority / ratings field that is much needed since ancient times, turns out to be possible thanks to the brilliant Zotero Special Tags column plugin [1].

Code to paste into the plugin: (I used moon here since there is no "empty star" emoji).

{
"5-star": "🌕🌕🌕🌕🌕",
"4-star": "🌕🌕🌕🌕🌑",
"3-star": "🌕🌕🌕🌑🌑",
"2-star": "🌕🌕🌑🌑🌑",
"1-star": "🌕🌑🌑🌑🌑",
"0-star": "🌑🌑🌑🌑🌑"
}
