Oh, awesome. Wish I knew that when I built my custom, ha!
One specifically for developing a better memory in general. Not as big as quantum limitless or limitless, and not as general as IQ and Cognitive Booster. Just something to develop all types of memory, including remembering names (which I commented earlier)
That stuff is in Limitless
Is limitless a Q core or is it available as a module? I always like the idea of a more specific module version of something broader like Limitless.
This one may have been mentioned here before but I feel like this would be such a gamechanger. Helping you to commit to your custom and avoid switching your stack.
A module to let you study in bed without falling asleep, especially when it’s cold.
Awaiting Virtuoso, the sales copy is already perfectly composed 
I love this idea. I think it would be a huge hit in the Q store!
More “Romance and Sex” modules
The one that gets you back on the study table and brave the cold.
A module that focuses directly on dominating social settings (like group settings for example) becoming the center of attention and the person all other want to speak to. Maybe also interwoven with slight healing that helps you embrace the needed qualities like for example being able to easily initiate conversations with strangers.
EDIT: Something like this would be just incredible. A module that makes you more social is truly missing in the q-store.
Extreme Study Motivation, similar with Extreme Exercise Motivation module
A/SPS: Body Odor
A module that increases your natural pheromone production, changes your body odor, heals bad breath and making women wanna kiss you just because you smell so nice, and - if you are really crazy - improve the taste of your sperm.
Mental resilience and extreme willpower module
Second this request. You could call the module Grit
Module for not getting bored by your habits aka. routine work. Do the habit on day 30 with as much enthusiasm as on day 1.
A module that brings dead loved ones to your dreams so you can communicate with them. To help you grieve, make peace with the loss and move on.
You manifested this one man!
Dude your great suggestion made it to the Q store. Love how SubClub truly listens to our requests and makes them into reality.
