Totally agree. It takes a while to "load" the project but then once it's loaded moving around a large codebase is a breeze but as soon at the code changes broaden and I slow right down cos I have to rebuild the map with the new additions. only way i can describe it: it's like loading google/apple maps and instead of it showing a low detail view with only the big roads displayed i'm loading the entire super details map, it takes a while but once it's loaded there's 0 lag.

also it's actually reassuring knowing someone else is similar, no-one in my life seems to work the same.
