While GitKraken and Git Tower don't directly support remote stashing for working across multiple machines, you can achieve a similar workflow by using dedicated branches for your work-in-progress changes. Commit these changes to a specific branch, then push to a remote repository. This allows you to pull the branch on any machine and continue your work. It's not as seamless as stashing, but it leverages Git's existing features to meet your needs. For a more streamlined process, consider scripting these steps.
