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

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

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!
