If you are installing/updating lots of packages via unreliable connection (e.g. wifi), it is common that some downloads fail due to network timeouts or other problems. Yast2 shows an error message, proposing abort, retry and skip actions. But there is no default action, so you have to check if this message appeared and press retry over and over. This is really inconvinient, since you can't just leave system updating and go get some coffee. And of course it makes web install total hell, since you download at least 1000 packages...
    What I would like to see is a timeout timer, wich would automatically "press" the retry button every e.g. 10 seconds. This would make system much more stable. Also, after some predefined amount of failed retries, system could try to skip the package. Of course, in some cases this behavior could be unexpected, so an appropriate switch could be useful.

Author suggests some ui fixes to make dialog more convinient,  and it is good, however without timeout it is just as bad as it was.
   Good luck=)
