Game Patch Update
The maps and app is updated to the new Diablo IV season, including a new area and some new filters.

Mon Mar 30 2026
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
