KillerNotes v1.3.1

1.3.1 adds backups and recovery, version history, trash, reusable note workflows, and deep KillerMCP integration.

Added

• Scheduled backups: Manage databases gains a Backups dialog to pick a folder, an interval and how many copies to keep. Copies are the database as it is, password and all, and one can be restored as a new database. Alt+B takes a copy right away.
• Version history: earlier versions of a note are kept as you work, one per sitting plus one before any conversion or replace-all, up to 50. Alt+H or the right-click menu shows them with a preview and puts one back.
• Deleted notes now go to a Trash section at the bottom of the sidebar, where they open read-only and can be restored or deleted permanently. Anything left there for 30 days is purged. Alt+Delete opens the trash (#20).
• Note templates: mark a group as the templates group from its right-click menu, and every note in it appears under "New note from template" and on Alt+T. {date}, {time}, {datetime} and {weekday} in a template are filled in on the way.
• Daily notes: Alt+D opens the note titled with today's date, creating it in a daily notes group of your choosing and from a template named Daily when you have one.
• Headings and an outline: Alt+1, 2 and 3 make a line a heading, Alt+0 puts it back, and the H button on the format bar steps through them. Alt+O opens an outline of the note's headings beside it; click one to jump there. Headings now export to markdown as headings.
• KillerMCP can search, inspect, create, edit, organize, color, import, and export notes through the open app.
• Italian, Russian, Kazakh, and Vietnamese localizations bring the complete app interface and killernotes.net to 16 languages.
• Checkbox lines: Alt+C or the format bar puts a box at the start of the line, a click ticks it, and Enter carries on to the next one. They export as markdown task lists and import back.
• Notes can be pinned to the top of their group or of the loose notes, from the right-click menu or Alt+P.
• F3 and Shift+F3 now continue through matching notes instead of wrapping inside one note (#18).
• The title bar now shows which notes database is open.

Changed

• Technical page diagrams now use portrait layouts so their labels stay readable in the two-column page.
• On first launch, the interface follows the Windows display language when it is supported.
• An open Markdown or HTML preview now refreshes as its source changes without losing its scroll position.
• The shortcut list now focuses on app-specific commands instead of repeating standard Windows editing keys.
• Standalone install and uninstall dialogs use Black/Purple; installer errors use themed dialogs. Installed Apps identifies the publisher as Steve the Killer.

Fixed

• Screen readers now identify the note list, editor, title, window controls, icon buttons, sorting controls, and custom dialog controls instead of announcing unlabeled glyphs or model class names (#22).
• Chocolatey package now installs the app instead of leaving the download in the Chocolatey tools folder.
• Maximizing or restoring the window now keeps the same part of a long note in view (#21).
• The font-size slider now stays responsive while formatting large selections (#19).
• Dropping a note directly onto a group now always moves it into that group (#17).
• Import, export, sharing and database export now use the family file picker, with complete filename tooltips.
• On the Sepulchre and Mourning themes the theme picker's radio ring, dot and label no longer vanish into the row's hover highlight; they turn white while hovered.
