Hi Rouslan, Well the idea is great and it should be good to be applied but that developers concern is also a big concern! But there is more about it, if we plan to cache that big file(we are certainly gzipping it?) over the browser(will substantially decrease more payload) then we have to purge the whole big file if even a single file among the list has been changed. Also minified versions sometimes causes error in gzipping and also if we merge it with another minified file. Dron Rathore
