Changelog

1.1.0

Redesigned report window in Valheim's own fonts and colours: cards per mod with severity colour, badges, number tiles and bars.
The report window (F7) now has tabs: Problems, Mods, Performance and, for server admins, Server.
Mods tab: compares your mods with the server's when you join (missing, different version, only yours) and shows a notice if they differ. Also lists mods installed twice and the slowest mods to load.
Performance tab: FPS (average and 1% low), worst frame, memory, garbage collections per minute, the world objects loaded around you grouped by type, and Mod Doctor's own cost.
Server tab (admins): server health, and for every player their mod differences and problems.
Server summary.txt now includes each player's mod differences.
New server option Server.ServerOnlyMods: mods players do not need, never reported as missing.
The report file is only rewritten when something changed.

Opaque, colour-coded report window (the default IMGUI skin was hard to read over the game).
Notices only appear while you are in a world; entering a world summarises mods already causing errors, and a mod is announced again when its problem gets worse. Occasional errors stay in the report without a notice.

First release: error attribution (stack traces and Harmony patch owners), startup failure recovery, classification and advice, log spam suppression, Thunderstore update check, in-game report (F7), and player report collection on dedicated servers.
