Many times I have a lot of changes in my working copy and I decide to commit these in a few separate commits.

To have these commits working, I would love to have the ability to stash only a few selected files to get rid of them temporarily, rebuild to see if the stuff works, and then commit.

Currently, there is only an option to stash all files. Stashing selected filed only is possible with Git in command line, however this is so impractical.
