 - **Glättung in zwei Stufen:** Während des Schreibens glättet ein 1€-Filter das Zittern, die Linie erscheint sofort. Beim Absetzen wird der Strich nachbearbeitet: Ecken (Knicke über 65°) bleiben erhalten und werden rund verbunden, der Druckverlauf wird geglättet, überflüssige Punkte entfallen, die Enden werden rund.
 - **Druckkurve** im ☰-Menü an den eigenen Stift anpassen (weicher/härter, Schwelle gegen Grundrauschen).
 - **Tasten am Stift** im ☰-Menü belegen: Radieren (Standard), Auswählen, Textmarker, Stift oder nichts – gilt, solange die Taste gedrückt ist. Jede Taste erscheint dort nach dem ersten Drücken.
-- **Radierer** in drei Modi: ganze Striche, nur den überstrichenen Teil (Teilstrich) oder nur Textmarker; die Größe stellt man in einem Menü wie bei den Stiften ein (wird gemerkt). Die Stiftrückseite radiert ebenfalls.

 - **Virtuelles Lineal** (`L`): verschieben, am Griff drehen (rastet bei 15° ein); Striche entlang einer Kante werden gerade.
 - **Nur ansehen** (👁 in der Werkzeugleiste): Stift, Finger und Maus scrollen und zoomen nur; die Werkzeuge verschwinden, nichts lässt sich versehentlich ändern. Erneut 👁 tippen, um zu schreiben.
 - **Platz schaffen** (↕ in der Werkzeugleiste): aufs Blatt tippen und nach unten ziehen – alles darunter rutscht mit, auch auf den folgenden Seiten. Was über ein Seitenende rutschen würde, beginnt auf der nächsten Seite; fehlende Seiten werden angehängt. Nach oben ziehen schließt leeren Platz. Ein Schritt für Rückgängig.

 - **Two-stage smoothing:** While you write, a 1€ filter removes jitter and the line appears immediately. When you lift the pen, the stroke is refined: corners (bends over 65°) are kept and drawn round, the pressure curve is smoothed, redundant points are dropped and the ends become round.
 - **Pressure curve** adjustable to your pen in the ☰ menu (softer/harder, threshold against base noise).
 - **Pen buttons** can be assigned in the ☰ menu: erase (default), select, highlighter, pen or nothing – active while the button is held. Each button appears there after it is pressed for the first time.

 Notebook app for pen, touch and mouse on Linux (tested on Zorin OS 18 / Ubuntu 24.04).
 
 ### Highlights:
+- **Pen without lag on Wayland**: Pen events reached the app only when something else woke it, so strokes trailed behind the pen or appeared only later. Every event from the compositor now wakes the app; it still uses no CPU while idle (Issue #53)
+- **Eraser removes text**: The whole-stroke and partial erasers now remove a text box – typed text or an inserted math result – as soon as they touch it. The highlighter eraser leaves text alone, images are never erased (Issue #54)
+- **Writing with the finger on Android**: "Draw with finger" (☰ → Input) is now remembered and starts switched on on Android, where phones usually have no pen. Before, it was off after every start, so after an update one finger only moved the page (Issue #50)
+- **Momentum scrolling with the finger fixed**: On Wayland, lifting the finger after a swipe could reach the app only together with the next touch, so the page stopped dead instead of gliding on. The app now keeps listening while a finger is on the screen, so the page glides after a quick swipe and slows down gradually (Issue #28)
 - **Nextcloud built in**: ☰ → Storage location → Nextcloud syncs the notebooks directly with your Nextcloud – also on Android and without a sync client. Enter the server address (private servers in a subfolder, with their own port or a self-signed certificate work too), sign in in the browser; the app gets an app password of its own that "Disconnect" revokes again. Syncing runs every 30 seconds and shortly after saving and keeps working offline; a page changed on two devices is kept twice, deleted notebooks and pages go into the trash on both sides, changes arriving for the open notebook wait until it is saved (Issue #49)
 - **Security update**: rustls 0.23.46 (TLS library for update checks and the Nextcloud sync) fixes a way for key material to end up in logs (Issue #51); ink-notes itself was not affected, as it doesn't keep TLS sessions
 - **Android toolbar fix**: The toolbar and menus stay clear of the status bar, the navigation bar and the camera cutout, so the topmost button (📚 notebooks) can be tapped again; in landscape the page is centered between the side bars. Nothing changes on Linux and Windows (Issue #50)
