+## This is for tracking UI-Tests migration progress for FancyZones Editor Module
+Refer to [release check list] (https://github.com/microsoft/PowerToys/blob/releaseChecklist/doc/releases/tests-checklist-template.md) for all manual tests.
+
+### Existing Manual Test-cases run by previous PowerToys owner
+For existing manual test-cases, we will convert them to UI-Tests and run them in CI and Release pipeline
+
+ * Launch Host File Editor:
+- [ ] Open editor from the settings
+- [ ] Open editor with a shortcut
+- [ ] Create a new layout (grid and canvas)
+- [ ] Duplicate a template and a custom layout
+- [ ] Delete layout
+- [ ] Edit templates (number of zones, spacing, distance to highlight adjacent zones). Verify after reopening the editor that saved settings are kept the same.
+- [ ] Edit canvas layout: zones size and position, create or delete zones.
+- [ ] Edit grid layout: split, merge, resize zones.
+- [ ] Check Save and apply and Cancel buttons behavior after editing.
+- [ ] Assign a layout to each monitor.
+- [ ] Assign keys to quickly switch layouts (custom layouts only), Win + Ctrl + Alt + number.
+- [ ] Assign horizontal and vertical default layouts
+- [ ] Test duplicate layout focus
+	- Select any layout X in 'Templates' or 'Custom' section by click left mouse button
+	- Mouse right button click on any layout Y in 'Templates' or 'Custom' sections
+	- Duplicate it by clicking 'Create custom layout' (Templates section) or 'Duplicate' in 'Custom' section
+	- Expect the layout Y is duplicated
+
+### Additional UI-Tests cases
+
+- [ ] Add test data and start → verify data is correct (custom layouts, template layouts, defaults, shortcut keys)
+
+- [ ] Create a new canvas - verify layout exists
+
+- [ ] Create a new canvas - cancel - doesn’t exist
+
+- [ ] Create a new grid - verify the layout exists
+
+- [ ] Create a new grid - cancel - doesn’t exist
+
+- [ ] Duplicate template by button (+ check default)
+
+- [ ] Duplicate template by menu (+ check default)
+
+- [ ] Duplicate custom by button (+ check shortcut key and default)
+
+- [ ] Duplicate custom by menu (+ check shortcut key and default)
+
+- [ ] Delete non-applied layout
+
+- [ ] Delete applied layout
+
+- [ ] Delete-cancel
+
+- [ ] Delete from context menu
+
+- [ ] Delete: hotkey released
+
+- [ ] Delete: default layout reset to default-default
+
+- [ ] Edit template and save
+
+- [ ] Edit template and cancel
+
+- [ ] Edit custom and save
+
+- [ ] Edit custom and cancel
+
+- [ ] Edit canvas: add zone
+
+- [ ] Edit canvas: delete zone
+
+- [ ] Edit canvas: move zone
+
+- [ ] Edit canvas: resize zone
+
+- [ ] Edit grid: split zone
+
+- [ ] Edit grid: merge zones
+
+- [ ] Edit grid: move splitter
+
+- [ ] UI Init: assigned layouts selected
+
+- [ ] UI Init: applied default - check params
+
+- [ ] UI Init: assigned custom layout, but id not found
+
+- [ ] Assign the same template but with different params to monitors
+
+- [ ] Assign layout on each monitor
+
+- [ ] Assign custom
+
+- [ ] Assign template
+
+- [ ] Assign shortcut key and save
+
+- [ ] Assign shortcut key and cancel
+
+- [ ] Reset shortcut key and save
+
+- [ ] Reset shortcut key and cancel
+
+- [ ] Set default layout + verify both prev and current after reopening
+
+- [ ] applied-layouts.json keeps info about not connected devices - verify they’re present after closing
+
+- [ ] applied-layouts.json keeps info about other virtual desktops
+
+- [ ] first launch without custom-layouts.json, default-layouts.json, layout-hotkeys.json and layout-templates.json
