GAG (Gadgets Against Grind) is a cross-platform utility mod where the goal of each item is to reduce the amount of "grind" a player will have to face during their day-to-day modded business, while (optimally) keeping a Vanilla feel to every item and not feeling too cheaty compared to using something like commands. Some of things GAG adds include:

A way to easily teleport your way out of caves (Escape Rope)
Hearthstones that can teleport you to your personal spawn point or world spawn, as well as a variant that you can bind to any location!
A No Soliciting! Sign to block certain pesky intruders from entering your base.
Different types of Dynamite for easier mining and fishing!
A way to tick accelerate blocks, Time-in-a-Bottle style (Temporal Pouch, might be reworked in the future)
Multiple ways to stop mobs from spawning near you temporarily, enabling you to mine in peace (Sacred Salt, Balm and Salve)
A Labeling Tool to rename your items on the go without consuming tons of experience
- (NEW!) With Pigment Jars, you can now give your favourite tools custom colored names!

Most parameters of these items are configurable by pack developers, and I personally recommend changing the recipes and / or disable some of the features entirely if you do not deem them a good fit for your pack. The defaults are all done with something close-ish to Vanilla in mind, so your mileage may vary.

More items will probably be added in the future as I can come up with novel (enough) ideas, or if I like a suggestion submitted to me on GitHub enough :P
