Major Layout Redesign
The header and navigation have been completely reworked across all platforms (Web, THGL Companion App, Overwolf) to maximize map area and create a consistent, streamlined experience.
Fewer Ads, More Map
- Desktop: some ads are hidden when the filter sidebar is collapsed, giving you a cleaner map experience
- Mobile: reduced from two ad containers (floating video + banner) to a single 320x50 bottom banner
- "Get AD-Free" badge made more compact
New Header Layout (Web)
- Replaced the left sidebar with a compact game switcher dropdown in the header
- Social links (Discord, GitHub, Reddit) now sit inline in the header on desktop, and in the nav dropdown on mobile
- Legal Notice, Privacy Policy, and Consent links moved into the nav dropdown on all screen sizes
- Removed the Info button — all its content is now in the nav dropdown
- Settings and Account buttons use outline style for better visibility
- Account icon changed from Heart to CircleUser for clarity
New Header Layout (THGL Companion App)
- Streamlined to just Settings, Account, and a burger menu in the header
- Hide Controls, Overlay/Desktop/Both toggle, and Live Mode always visible in the header on all screen sizes
- Burger menu contains social links (Discord, GitHub, Reddit), Debug Snapshot, and legal links
- CircleUser icon for account, consistent with web
New Header Layout (Overwolf)
- Rebuilt header with own 32px design (no longer shares the 54px web header)
- Game switcher with compact icon fits the smaller header
- 2nd Screen Mode, Live Mode, and Hide Controls always visible
- Settings and Account as outline buttons, burger menu for socials, debug, and legal links
- Debug Actors button now a compact icon instead of full-width text button
- "Show controls" hint text reduced for a cleaner overlay experience
Grouped Map Controls
- Map controls (Compass, 3D, Zoom, Home) and action buttons (Whiteboard, PeerLink, Node, Drawing) are now compact grouped strips
- On mobile, a single button opens a popover with all controls
- Action clicks close the popover; map control clicks don't
- Consistent 32x32px button sizes across all groups
Collapsible Filter Panel
- Filters collapse on mobile by default for more map space
- A floating "Filters" button appears when collapsed
- Slide-in/out animation via CSS left positioning
- Expand/collapse toggle for small/large filter mode on desktop
Marker Tooltip Improvements
- Tooltips now render outside the map container (no longer clipped by overflow)
- Works correctly in small overlay/minimap windows
- Tooltip closes when hovering over UI overlays (controls, filters)
- Tooltip won't open for markers hidden behind UI elements
New Map Renderer on Overwolf
- The Overwolf apps has been updated. See https://discord.com/channels/320539672663031818/1166078913756270702/1485611369339424939 for the Map Renderer details.
Other Improvements
- External nav links restyled as pill buttons with borders for better visibility
- Locale switcher shows globe icon and highlights active language
- Brand text shows full game name on large screens, "TH.GL" on medium
- Mobile banner ad aligned to bottom-left
- "Get AD-Free" badge made more compact
- Removed unused dev-log utility
- Cleaned up private-node debug logging
... and several more Bug Fixes

New Map Renderer
The interactive map has been completely rebuilt with a new WebGL2-based renderer, replacing the previous engine (leaflet). This affects all game websites and the THGL Companion App.
What's improved
- Map rendering is significantly faster and smoother, especially when zooming and panning
- Icons and markers are rendered more efficiently, even with thousands on screen
- Smoother player movement
3D Perspective Mode
- Right-click and drag to tilt and rotate the map
- On mobile, use two fingers to rotate and tilt while zooming
- Height indicators show elevation differences between markers when tilted
- New compass and map controls (3D toggle, zoom, reset view) next to the existing action buttons
New Settings
- Dynamic icon sizing: control how marker icons scale when zooming in and out (toggle + intensity slider in Icon Sizes settings)
- Trace line style: choose between dots (default) or connected line
Tooltip Improvements
- Tooltips now reposition automatically to stay within the map area
- Improve scrolling inside long tooltip descriptions
Text Labels
- Labels scale consistently with zoom level
Other Changes
- Responsive ad layout: smaller ad format on short browser windows to avoid overlapping map controls
Overwolf in-game overlays are not updated yet — I'd love to get your feedback on the new renderer first before rolling it out there. Let me know if you notice anything off!
