Below is a video that shows the transitions between selecting an album from the album grid and opening the album details. This was recorded on an old galaxy s3 running Lineage OS (7.1.2) so it appears the actual recording is a bit glitchy. The Image showing over half of the floating action button doesnt actually happen on the device.
Progress might seem slow but once a lot of the essential capabilities are written, they will be reusable on almost all the other views (IE artist detail view and genre detail view will be pretty similar to the album view, so it wont take long for me to add). Next up on my list is adding the 3 dot buttons / context menus on to the list / grid items.
