 - make column of entry field greedily consume all unallocated space
 - status area looks awful
 - add button with GTK_STOCK_UNDELETE for "undelete" to menu bar
+- edit names/values/etc. in place if possible
 
 Bugs:
 - default silk width has no business being hard-coded in obj.c
 - undelete only works if not much has changed since the deletion
+- re-center while dragging confuses the save-under mechanism
 
 Code cleanup:
 - merge edit_unique with edit_name
