Shkarko KillerNotes 1.3.2

1.3.2 polishes copy and paste, markdown conversion, the markdown and HTML preview, and undo.
Added
- A mode button on the format bar shows whether the preview is in Source, Rendered or Split view, and cycles it like F4.
- The divider between the note and the preview in Split view can be dragged to change their widths.
- A chevron on the linked-from strip folds it into the corner of the note with a short slide, leaving its count to reopen it.
- Home, End, Page Up, Page Down and the arrow keys scroll the rendered preview. Ctrl+Home / End now appears in the F1 shortcut list.
Fixed
- Copied text now keeps its links, lists and emphasis when pasted into browsers, mail clients and Office.
- Pasting web or chat text with links now keeps its paragraphs instead of joining them into one.
- Converting a note to markdown no longer puts a backslash before every underscore, asterisk and bracket.
- Holding Ctrl+Z no longer undoes several organizational actions at once.
- Markdown notes always offer the preview and F4, even when their text has no headings, links or bold.
- F4 now works after clicking into the preview.
- Copy on a note image now places the image on the clipboard.
- The preview now fills its pane to the edges, with rounded corners, film grain and a slim scrollbar that match the editor.
- The outline pane now runs to the edges of the note with film grain and a rounded bottom corner like the rest of the editor.
- SketchPad no longer opens with a horizontal scrollbar. The blank sheet fills the window it opens in.
- On Greed, Blood and Cyanotic, menus and the format bar now sit a clear step darker than the window instead of blending into it.
- The boxes inside About now use the same color as the note pane, so About reads like the app: dark frame, lighter content.
- The database name in the title bar is white in the 98SE theme.
