The Maintenance window has a drop-down list where I can select which albums it should run on. When I have hundreds of albums in several collections, finding the one I'm currently working on so I can synchronize that album's metadata and regenerate thumbs is not easy. I ask that you please make it automatically choose the album currently opened in the main digiKam window. (the same way you recently fixed the BQM tool to show the current album when "Use original album" is not selected.) Reproducible: Always
This is confirmed on Ubuntu-Gnome 16.04 x64 and Windows 10 x64. Perhaps a button to just goto current album and leave the selecting or deselecting up to the user?
