v0.4.0 | 2026-06-10
* Added **Height filter** to step down rendering of transports, pillars, and layout entities from level 6 (all visible) to level 0 (underground only)
* Added default hotkeys `PageUp` (increase visible level) and `PageDown` (decrease visible level)
* Added height filter setting and customizable primary/secondary hotkeys in Mod Settings under **HEIGHT FILTER**
* Protects hidden entities from selection to prevent accidental interaction or demolition
* Updated Swedish translations and synced locale fallback strings across all supported languages

v0.3.1 | 2026-06-09
* Fixed: settings save default failure ("Save failed: Invalid path") by resolving the mod folder path correctly
* Fixed: settings save default validation to successfully write the configuration file even if values match currently stored defaults
* Updated **Restore defaults** tooltip to clarify that it does not automatically save defaults to the configuration file

v0.3.0 | 2026-06-08
* Migrated **Instant build mode** (configurable in Mod Settings) which instantly finishes construction, deconstruction, upgrades, and downgrades without materials or unity from Moriarty's Utilities++ (THANKS!)
* Migrated **Transport cleanup tool** (default `Alt+Del`) to instantly remove disconnected belts and pipes from Moriarty's Utilities++
* Added **Restore defaults** and **Save as config** buttons to Mod Settings
* Added **Markdown number format** setting with Auto, English, Local modes
* Changed Markdown export to use vanilla game translations for workers, electricity, and computing
* Fixed: Markdown export products and entities with identical names do not merge

v0.2.0 | 2026-06-04
* Added **Mod Settings** window, opened from the top-right **M** button or with `Alt+M`
* Added **Markdown table language** setting with English, Local, Both, and Hybrid modes
* Added per-save persistence for Designer Toolkit settings through `dtkSettingsStateJson`; `markdown_table_language` in `config.json` is used only to initialize saves without persisted settings
* Added Designer Toolkit translations for English, German, Spanish, Italian, Portuguese, Russian, Swedish, and Chinese

v0.1.0 | 2026-05-31
* Added **Update blueprint** button in the blueprint placement panel: re-selects an area to replace an existing blueprint while preserving its name, description, overlap settings, and book position
* Persists the last-open blueprint book folder to config.json and restores it when the blueprint book is reopened
* Blueprint stats row in the Detail panel: shows total workers, electricity, computing, and maintenance for all entities in the selected blueprint
* **Copy as Markdown** in the blueprint detail panel: copies a Markdown-formatted summary to the clipboard - heading, description, Components table (A-Z), Construction table (A-Z), and Operational table
* **Copy as Markdown** in the blueprint folder detail panel: copies a wide Markdown table of all blueprints in the folder tree (recursive); each blueprint is a row, with a Folder column for the relative sub-folder path and dynamically discovered stat/cost columns (A-Z); rows sorted by folder then by blueprint name
* Fixed: electricity values now always use `.` as the decimal separator regardless of OS locale
