Dear Chimera developpers, Thank you so much for your work and your dedication! Having used Chimera quiet intensively recently, I have listed a few suggestions for your consideration. Suggestion #1: Tools > Structure Editing > Change Chain IDs: lacks a "restrict to current selection" button (would allow to name various domains of a single protein) Suggestion #2: Named selections: - I did not find out how to edit them (even "suppress" would add flexibility and reliability). - The list is not refreshed as session is closed (Windows). Thus opening and closing sessions one after the other results in merging the "Named selections" of all sessions successively opened... Suggestion #3: The 'window-size memory' feature that was devised by Eric for the File>Open window would be of interest to most windows: model panel / matchmaker / match / etc... Could you make it a general feature of the various windows in the GUI? (It would also be a plus if the preferred location of any of these windows could be memorized as well.) I trust your expert appreciation whether these suggestions are to be implemented sooner or later... or never :-( Thank you for your consideration and for your help! Antoine
