In the task progress info that can be expanded by the blue upwards arrow in the lower right corner, KMail currently reports "Syncing folder 'foo'". If there are multiple layers of folders, it may not be clear to the user which folder exactly is currently being synced. E.g. there may be folders of the same name in different places of the tree. Thus I suggest to display the full path to the folder and not just its name. Reproducible: Always
Indeed but we can't for the moment. We just have info about file.
