I use 'find' a lot to look for files I've made. The most often used command on my system is going to be 'ls'. I don't think that I am unusual for this.
So that's a big reduction in usability for me. I frequently drop to shell for all sorts of trivial things like that. Slows me down somewhat.
Having the ability to see files grouped by dates would actually be very useful since at work I typically see my time fractured. Over a week's time I may be working on 4 or 5 different things, some tasks taking short amount of time, other tasks taking several months. Often they are not directly related. I try to organize stuff by folders and whatnot, but I forget the names of folders and end up with a lot of clutter in my home directory.
I maybe working on something for few days time and end up getting side tracked for quite a while with a different emergency or new, more important task. Often I will simply lose my place and forget exactly were I left off. Being able to go back and see what files and programs I was using a while ago would help a lot.
Maybe programmers are used to having very focused, long-term tasks, were you are using the same stuff day in and day out, but that's not true for lots of people.
