A vanilla-like experience made for my friends and I with some quality-of-life changes.
There are quite a few optimization mods in like RandomPatches, FastWorkbench.
But this pack is mostly about quality of life like Inventory Tweaks and MouseTweaks which allow you to scroll when taking items out of chests. Other things include Dirt2Path which allows you to un-pave dirt when you accidentaly clicked. Simple Harvest for right clicking to harvest - just quality of life things.
Other mods that actually add or change things are kept to a low amount but these are:
Journeymap - for mapping out the surroundings.
FTBUtilities - claiming your area and chunkloading the world
OpenBlocks Elevator - To reduce the ladder climbing boreness, also adds more options in houses & secret bases.
Traverse - New biomes since they can be really cool to build in.
Quark - A lot of things, from quality of life to misc things like a slime chunk checker tool.
