From the author's README on Thunderstore

Save your favorite skate spots per map and travel back to them from an in-game SpotList.

Getting started

Requires ReSkate 2.1.2 with plugins enabled. Press P to open or close SpotList, then choose Save Current Spot. Select Travel on a saved spot to return. Change the keyboard shortcut or enable an optional L3 / LB + L3 controller shortcut in SpotList. D-pad navigates the window; A selects and B closes it. The Spot Pins page is also available under ReSkate's Plugins menu.

Give spots custom names and notes, mark favorites, search, sort by distance, and control floating markers globally or per spot. Use History and Return to revisit recent destinations. Delete and position updates ask for confirmation. Close on Travel is optional.

Saved spots and settings are local. Teleport history is session-only. SpotPins does not set the game's native session marker automatically. Teleporting in multiplayer is subject to host rules.

Install SpotPins

You need ReSkate and your own copy of skate. on Steam.

Open ReSkateLauncher.exe and go to MODS.
Search for SpotPins and click install. The launcher also installs anything it depends on.
Press PLAY. In game, the MODS tab of the ReSkate menu (Insert) turns it on and off.

Or install it by hand: download the .zip and drop it on the launcher window, or unzip it into its own folder in Mods\ beside Skate.exe.

Maps show up in the ReSkate menu's level list. To join a server running a custom map, you need the same map installed. If the game won't load after installing, see known issues.

skatemods doesn't host or review this mod. The download comes straight from Thunderstore. Only install mods you trust, because scripts can run code.
