## Problem to solve
Loading the new Web IDE is fast, but there are times when you want to jump right into working on a file. Right now you have to wait for the welcome screen to load (which is a separate bug that we're working on) and the file list to be populated.
## Proposal
Prioritize loading the file or files opened from the repository before displaying the welcome screen or file tree.
## Questions
Is this even possible? Given the file system needs to be loaded, do we even have the contents of the _opened_ file before we populate the file tree? Can the order of these be reversed or is there a dependency on loading the FS first?
