On a deep search, the user may be skipping large numbers (eg 100). It would be helpful to have the option to display only the versions that have actually been cbecked, otherwise, a lot of scrolling has to be done to find what you are looking for. Also, the next action after such a search is invariably to want to search the versions between two adjacent results in the list, it would help if this was made easy to do - perhaps a button next to each version which initiates a new search starting at that version.
I will replace the non checked versions by a text saying [skipped n versions].
The link to the "next step" is a great idea. Unfortunately I'm not yet able to access the date information of a revision, since it has a different structure in various languages.
Still working on skipping the output of skipped versions, but meanwhile "search from here" has been implemented.
