Update 1.12.1

- Added a reroll helper that shows previews for multiple seeds at once and allows pinning favorites
- Fixed preview window not opening when a tile is clicked in some circumstances
- Fixed compatibility with RimThreaded

Update 1.12.0

- Added option to exclude caves from previews (makes preview generation faster)
- Added option to hide individual toolbar buttons (in case there is some you never use)
- Added option that locks preview and toolbar position to prevent accidental dragging
- When "WorldEdit" mod is installed, a new toolbar button will be displayed for easy access to it
- When "Prepare Landing" mod is installed, a new toolbar button will be displayed for easy access to it
- The preview will no longer auto-open immediately after switching to world map (no more lag spikes)
- Fixed UI sliders not working correctly after they were changed in a recent RimWorld update
- Reworked many Harmony patches into transpilers for better mod compatibility
- Added compatibility for the "BetterLoading" 1.4 fork (experimental, may be unstable)

Update 1.11.0

- Integration with Map Designer: Open it on the world map and Map Preview will act as a live preview for your changes. Thanks to @Zylleon for the code changes on Map Designer's side that were needed to make this work.

- Moved the buttons from the preview window to a separate toolbar, so they no longer cover parts of the preview.

- Added a button to quickly reroll the world seed (during starting site selection)

- Preview will now automatically refresh when you change the map size (also works with Better Map Sizes mod)

- Reworked how seeds for rerolls are chosen. They are still deterministic, but now tied to world seed and tile.

- Fixed reroll button being unavailable for tiles that have quest sites on them.

Update 1.10.3

- Added tooltip that shows terrain at hovered position in preview
- Fixed compatibility with "Performance Optimizer" mod in 1.4
- Some minor bugfixes

Update 1.10.2

Added basic map seed reroll feature. It is disabled by default and can be enabled in the mod settings. The main difference to the Map Reroll mod is that the rerolling happens on the world screen, before the actual map is generated, which is better for mod compatibility.

Update 1.10.1

- Fix for RimWorld version 1.4.3514 and later

Update 1.10.0

Support for RimWorld 1.4 is in early beta and likely unstable. Please report errors and other issues.
In 1.4 this mod is now fully self-contained and no longer requires any dependencies such as HugsLib.

- Fixed a bug that caused terrain to generate slightly differently than in vanilla.
- Added support for non-standard map sizes, and added integration with the "Better Map Sizes" mod.
- Reworked how Harmony patches are applied to improve performance.

Added compatibility patches for the following mods that caused preview errors:
- Save Our Ship 2
- Startup Impact
- Fish Traps
- Animal Traps

- Added integration with new Geological Landforms features
- Small bugfixes and improvements

Added a patch to prevent region updater errors (with Dubs Bad Hygiene and some other mods)

Improved performance of World patches.
