0.6.0 — Application Settings#

Released.

Per-project application settings stored in .VIS/settings.json, accessed via Project.Settings, surfaced through a built-in tabbed Settings window.

Storage & API#

ProjectSettings (VIStk/Structures/_Settings.py) — project.Settings.get(key, default) / .set(key, value) / .save(), backed by .VIS/settings.json (new VINFO.p_settings path).
get resolution order: stored override → explicit default argument → framework DEFAULTS table → None.
A full default settings.json is generated at VIS new and on first Host launch (ProjectSettings.ensure_file(), idempotent) so all options are visible/editable; in memory only genuine overrides are tracked and save() writes the complete resolved set back. A missing or corrupt file falls back to defaults without crashing.
effective() (full resolved map, for the UI), reset(key), __contains__, and a dirty flag — the Host skips the shutdown write when nothing changed.
Saved automatically on Host shutdown. The capture commits only after every window has closed without veto, so a vetoed quit leaves settings untouched.

window.default_width / default_height / default_align (center + 8 compass points) / min_width / min_height applied to the session’s first window.
window.remember_geometry — restore the primary window’s last size and position.
window.fullscreen_on_launch — open the first window maximized.

host.start_with_os — toggles the Windows startup-registry entry (_register_startup / unregister_startup), reconciled on Save; disabled and not persisted over on non-Windows.
host.remember_tabs — reopen the previous session’s screens as tabs. The max_tabs limit is bypassed during restore so a remembered session isn’t truncated; screens no longer in the project are dropped silently.

appearance.font_family / font_size applied at launch to Tk’s named fonts (TkDefaultFont etc.), which default and ttk widgets inherit.
appearance.color_scheme — stored placeholder for the styles system (no effect yet).
Live re-styling of already-open windows is deferred to 0.6.1.

notifications.enabled (stored; consumed by the 0.9 Toast widget) and notifications.duration_ms — now the default InfoRow.show_banner duration when a caller omits it.

Modal, tabbed (ttk.Notebook) window opened from a framework-provided HostMenu > Settings entry present on every window. Save / Cancel / Restore Defaults; controls seeded from effective(); Save writes overrides-only and rejects negative / non-numeric numeric input.
host.register_settings_panel(name, setup_fn) — apps contribute their own tabs; setup_fn(parent_frame) builds into the tab body (mirrors a screen’s setup). A panel that raises shows an inline error rather than a blank tab.

The spec’s tray items (start-minimized-to-tray, a tray Settings entry) were dropped: the 0.5.3 always-Host refactor removed the system tray, so the Host now lives only as long as its windows.
Remember-open-tabs is a screens-only restore: the open screens reopen as tabs in one window; split-pane layouts and multiple windows are not reconstructed.
Window-size settings apply to the session’s primary window; drag-detached / popped-out windows keep the default size.
