Klok is undoubtedly a great tool for me, I use it all the time for keeping track on multiple projects.
It would be great if you could continue working on an entry that you have stopped working on previously (specifically an entry as opposed to a project).
Currently the right click options when you have selected and an entry are: Remove Entry, Edit Entry and Start Working. If you select start working a new entry is created rather than continuing on the one you have selected.
I'd like to be able to continue working on a specific entry without as new entry being created if possible.
