Description Johannes Wienke 2010-04-08 19:54:07 UTC

Version:           trunk (using KDE 4.4.2)
Installed from:    Archlinux Packages

The new setup page to chose between the different database backends does not provide good defaults. If you initially switch to mysql from sqlite, no defaults are provided except for the schema names. They are filled with the location of the old sqlite database, which is completely wrong. Especially the port should be set to the default mysql port.

Moreover, no "What is" texts are defined. Some questions that need to be answered:
 * Why do I need to different schemas for data and thumbnails?
 * Can thumbnails-db and album-db be the same schema?

I just noticed that an empty host name defaults to localhost. This should be visible in the gui.

To host DB thumbnails to a separate place. Whith huge collection, DB file will bloat quickly.

So add this to the tooltip. This will definitely help.
