+## 2026-05-22 – UI: Einheitliche Icon-Buttons für Bearbeiten/Ansehen/Löschen
+
+- **Bleistift-Icon** (transparent, ohne Hintergrund – Stil der Direktverbindungs-Kacheln) ersetzt alle „Bearbeiten"- und „Öffnen"-Buttons in `accounts/list`, `customers/show`, `customers/list`, `suppliers/list`, `useradmin/list`, `assets/list`, `belege/list`, `invoices/list`, `invoices/show`
+- **Auge-Icon** (Kästchen mit Auge) ersetzt die PDF-Buttons in `invoices/list` (PDF), `invoices/show` (PDF herunterladen) sowie den „Ansehen"-Button in `tax/ustva_index`, um „nur ansehen" visuell vom „bearbeiten" abzugrenzen
+- **Papierkorb-Icon** (transparent, Danger-Farbe) ersetzt alle „Löschen"-Buttons in `accounts/list`, `invoices/list`, `useradmin/list`, `suppliers/list`, `assets/list`, `belege/detail`, `settings/bankimport`, `bank/fints` und `settings/form`
+- **Plus-Icon** (rund, btn-primary, 1,8rem) ersetzt alle „Neu anlegen/erstellen/hochladen"-Buttons – Topbars (`bank/fints`, Kunden, Lieferanten, Rechnungen, Belege, Wirtschaftsgüter, Konten), Dashboard-Schnellzugriff, Card-Header in `customers/show`, Aktionsspalte in `customers/list` und „Position hinzufügen" im Rechnungsformular
+- `bank/index.php`: Button „Öffnen" → „Aktivieren" (Status-Toggle, semantisch eindeutiger)

 ## 2026-05-21 – Feature: FinTS-Direktverbindung + Vereinheitlichung der Bank-Importquellen
 
 - **FinTS-Abruf** für Comdirect, DKB und weitere Banken über `nemiah/php-fints` (PHP-Lib für HBCI/FinTS 3.0). Leseabruf mit PIN; TAN-pflichtige Aktionen werden mit klarer Fehlermeldung abgebrochen
