Changelog

1.0.1

Renamed from SeneaL UI Radar to SeneaL Radar: it is an add-on, not a part of the interface. On Thunderstore it is the new package SeneaL_Radar; remove the old SeneaL_UI_Radar. Settings stay (same config file).
Traders without a name in their data (the Bog Witch) show their name on the world map card instead of an empty title.
Creature stars on the card are written as a number: the star glyph is missing from SeneaL UI's font and showed as a box.
New icon to match SeneaL Recycle.

First release: creatures around you on the minimap and the world map of SeneaL UI ([Radar] LargeMap turns the world map off). Soft dots with a dark rim that read on any ground: monsters red (a monster that hunts sends out a red ping), big dangerous monsters (500+ health: trolls, abominations, starred elites) a red diamond, bosses a gold badge with a star and a slow halo, traders (Haldor, Hildir, the Bog Witch) a coin badge, peaceful NPCs such as the Dvergr blue, tamed creatures green, animals pale, fish (optional, [Radar] Fish) small blue fish that turn the way they swim. The markers sit under the map pins and never leave the minimap circle.
Point at a creature on the world map for a card with its face (its trophy), name, stars, health, what it is doing (hunting, calm, tamed…) and how far away it is.
Settings in SeneaL UI → F7 → Add-ons with a legend of every marker (and in seneaL.valheim.ui.radar.cfg): on/off, range (10–200 m, 80 by default), world map, animals, tamed creatures, traders and NPCs, fish.
Servers running SeneaL UI 1.1.7 can limit the radar ([Server] Radar = On / MinimapOnly / Off, MaxRadarRange, RadarMonsters) or forbid the add-on; its card says what the server allows and greys out what is locked. On a server without SeneaL UI the radar stays off, like the mod's other gameplay features.
Its cost shows as its own addon.radar line in SeneaL UI's debug timings (F7 → General → Debug).
