When RStudio opens, it loads the project you worked on last. If the rproj-file has moved, been deleted or is on a disk that is not connected at the time of opening, Rstudio closes the project and goes back to a non-project version. However, when this happens, the project is also removed from the project menu in RStudio. I use different drives that at times are unavailable to RStudio which means that projects often get deleted from the project list.
My request is for RStudio to not delete the project from the project-list just because it is unavailable one time I open RStudio.
