gmb start -> menu -> add files or folder ....

gmb 1.0.2

gmb 1.1.3

gmb 1.1.3 album picture is not view.

why ???

Yes, sorry, in the v1.1.x branch, the auto-selection of album picture is not yet implemented. But you can still select pictures manually (right-click on album name). Also, if you migrate from v1.0.x to v1.1.x (if the tags file exist, but not the gmbrc file) the album pictures selection will be preserved.

The lack of this feature is one of the main reasons the v1.1.x branch is still in alpha and not in beta. It will probably be implemented in v1.1.5 (I will release a v1.1.4 soon)
