Hello, thanks for pointing out your contributions. I'll need to look into the history to see the file selector and compare it with John's selector and include one of these to fill the missing functionality. But this will wait for until I have dragged McCLIM towards the release (I'm fixing regressions and testing things since December with that single goal in mind :). Looking into git history you were active between 2005-2006 commit-wise. I know that this does not close the topic of contributions, because there are mailing lists and other projects like closure or beirc; that said going too deep into details is beyond my capability, so I'm going to trust git history and past contributor testimonies. Sorry for missing your these, they are certainly non-negligible. I've updated the documentation. The added sentence is: Max-Gerd Retzlaff (2005-2006) worked on panes and dialogs, improved clim-listener, and wrote the extensions Conditional Commands and tab-layout, as well as the demo Town Example. I've also updated the sketch on the server (https://mcclim.common-lisp.dev/static/documents/3d6249-mcclim-doc-sketch.htm...). Thanks, Daniel PS I've just checked in git history around 2006 (after your last commit), and there is no code that contains "file.*select", so I guess it was never committed.
