My experience to select modules in the Q store is poor!
With increasing modules, the experience is getting more difficult.
I sat to select modules for a new custom twice, and I quit half way both of the times.
To be absolutely honest, on my smart phone, the experience can be better no doubt.
While scrolling bdown the list, I open my selection modules in a new tab, then reach the bottom of the page and hit more to load more modules and this process continues untill I reach the last module. During this process, if I touch over any module by mistake I get into the page of that module. When I hit back, I have to start from the top all over again.
