The first thing you’d probably be interested in is how Sublime handles projects. Start by dragging a folder into it. This will open the folder in Sublime. Next go to the Project > Save Project As… menu and save it with a nice friendly name. Once you’ve done this with at least two folders, you can use ctrl+alt+p to quickly switch projects. This is awesome because each project keeps track of your window configuration and open files.
To upload files to a web server and work with SVN (from within the editor), you’ll need to install a couple of packages. Most users use the package manager I built called Package Control because it makes installing and keeping packages up-to-date really easy.
I wrote two packages, SFTP and SVN that sound you like be interested in. The both currently sell for $16 each, or $27 combined. There are some other free FTP-related packages available via Package Control, plus two Tortoise SVN packages that are also free. See wbond.net/sublime_packages/community for the full list of packages available via Package Control. You can also install other packages off of GitHub by using the “Add Repository” command.
There is a lot of flexibility and power available in Sublime, and most users that I’ve shown in to have really come to love it. It takes some time to really appreciate everything that it includes and what is possible.
I gotta get back to support requests. Good luck!
