/* TODOS:
1. bei zu vielen todos rutscht irgendwann das todo list popover nach oben,
weiter rumspielen mit max height bis es sich schön anfühlt aber zzz sleep time
2. unabhängig von window size ist die app irgendwie ein ganz klein wenig höher als die view??
Vielleicht margin oder padding irgendwo, oder doch die flexboxen, müsste ich mal genauer anschauen
3. State awareness, wenn neue Karte gesaved wird während existierende Karte bearbeitet wird werden änderungen verworfen (LoadPage UI Updates) und Delete wirft eine Fehlermeldung
Entweder Edits blocken, wenn eine neue Karte gerade erzeugt wird (einfach, yippee) oder State merken (schwieriger, wenig payoff)
4. Auf kleinen Screen sizes verschwindet der Add buton unter dem header.
Media query mit margin, bisschen rumspielen um korrekte Höhe zu finden. (Wenn margin immer da ist UI nicht mehr zentriert auf medium-large screens)
5. Beim Karten rendern und editen user input sanitizen
Schauen wie ich dann am besten text content style, ohne spans zu benutzen
6. Initial render lässt pagination buttons active obwohl eigentlich alles richtig gesetzt ist. Solution ist das rendering Promise-based zu gestalten.
Hacky workaround gefunden aber nicht schön
7. Beim Entries einfügen in Seiten > 1 wird die Karte am Anfang angezeigt (Index 5*currentPage), aber bei 0 drauf-unshifted und verschwindet aus der View. Seems unintuitive.
Entweder an die Stelle einfügen, oder bei Add auf Seite 0 forcen.
8. Dark mode colors rumswitchen
9. Change all references to delete button to done button or similar, sounds more positive :D
