With the recent addition of Fuseki search and the upcoming "free" pattern search, it became useful to be able to specify which databases should be searched by those functions.
Here is how - in the next update - the Database tab will look in the Settings dialog.
I have to apologize about the need to rebuild "Free Search" databases again with the next update. I decided to implement more functionality than Kombilo has, namely the ability to sort search results on player rank, date, komi etc. In order to be able to add this functionality, the databases have to change.
However, the new "Build database" Wizard will be easier to use, not requiring user interaction for every database.
