Its a pain to remember to download a zip from the plugins topic, take the installer out of the zip (because the zipped extension is often behind the SVN version) and copy it to the TWiki installation to run it there.
How easy it would be if the installer was in SVN.
No way, Jose! If you want to install from svn, use
. Installers and zips are derived files and are not kept in the repsitory.
