v0.4.0

MarkMello can now hold a whole folder open, not just one file at a time.

Folders and tabs

• Open a folder and its files show up in a sidebar on the left — Ctrl+Shift+O, or drop a folder on the window. Every file is listed; the ones MarkMello can't read are there but greyed out.
• Documents open in tabs. Each tab keeps its own editing state, scroll position and unsaved changes, so switching between files never costs you anything.
• Search by name filters the tree as you type; Esc clears it.
• Create, rename, duplicate and delete from the tree or its right-click menu. Deleted files go to the system trash, not into thin air.
• Files edited outside MarkMello are picked up automatically: the tree updates, a renamed file keeps its tab, and a deleted one closes it — unless you have unsaved changes there, in which case you're asked first.
• A second folder opens a second window, each with its own tabs. Reopening a folder brings back the tabs and expanded folders you left there.
• Ctrl+B hides the tree when you want the page to yourself.

Also in this release

• Find in a document — Ctrl+F, with matches highlighted as you type. Thanks to @mjalalimanesh for the contribution.
• An option for a window border, for desktops where the frameless window blends into the background.
• The Windows installer creates a Start menu shortcut again, and installing for all users now works as chosen.
• Typing in the editor no longer rebuilds the whole preview on every keystroke.

Opening a single file is exactly as fast as before — the folder machinery is only built when you actually open a folder.
