App to remember open app/file & browser window and their placement Is the an app or utility for the Mac (Mavericks - in particular) that will allow me to save everything I have open (apps w/files, various browser windows &amp; tabs) so that they can be reopened later?

I do a lot of research for various projects. Many times I can't complete the research in one sitting and have to try to remember what apps and more importantly what search rabbit trail I had gone down. It would be so much easier if I could take a "snapshot" of what is open, where it is at, save it as a profile / task group / desktop config (saving their size and location on screen) - call it what you want, then reopen it later.
Safari can save all open tabs from a single window &amp; reopen them with one click. Bookmarks Menu->'Add Bookmarks for these n Tabs'. 

Not certain for other apps, though as a workaround you could save copies of open documents all to the same project folder &amp; reopen from there.
