[gbl]

Already in the modpack, updated to 1.16:

https://www.curseforge.com/minecraft/mc-mods/beenfo
https://www.curseforge.com/minecraft/mc-mods/giselbaers-durability-viewer

New suggestions - all of them work client side/do not need server installation, though BlockMeter profits from being on the server):

https://www.curseforge.com/minecraft/mc-mods/blockmeterfabric (create block outlines, share with others, help with collaborative building)
https://www.curseforge.com/minecraft/mc-mods/grid (show a grid of lines, blocks, or circles, highlight mob spawn blocks and biomes)
https://www.curseforge.com/minecraft/mc-mods/randomblockplacement (auto switch between inventory positions when placing blocks to create random-looking walls or floors)
https://www.curseforge.com/minecraft/mc-mods/worldtime (show ingame time, wallclock time, and ingame position anywhere on screen)

https://www.curseforge.com/minecraft/mc-mods/easiercrafting - on-click crafts on crafting table, brewing stand, loom; show recipes you can craft with your current inventory
https://www.curseforge.com/minecraft/mc-mods/easierchests - quickly move complete rows, columns, or matching items between chests and inventory, sort chests (even when not installed on server)
https://www.curseforge.com/minecraft/mc-mods/easiervillagertrading - execute a single trade or as many trades as possible using the standard villager gui

RE: https://www.curseforge.com/minecraft/mc-mods/worldtime, the map included in the pack https://www.curseforge.com/minecraft/mc-mods/just-map-unlimited already displays world time and position, so there is  some feature overlap.

https://www.curseforge.com/minecraft/mc-mods/easiervillagertrading would conflict with https://www.curseforge.com/minecraft/mc-mods/speed-trading that was made specifically as a request for this pack (I did not know easiervillagertrading existed.) They both solve the same problem in different ways.
