I think that window of Loader in SQX isnt such good(and nice). I miss there search field as is in the attached picture. Its very usefull for me, because I have strategies sorted in subfolders and when I want load all of the strategies at once I only go to parent folder and write to search field "str" and it search also in subfolders. After that I only select all of the finded strategies. I dont have to load strategies manually from every folder separately. That is how it works in other software.
