+This is good opening for (eventually "fixing" e.g. library interface...);
+in its current state I can come up 2 (easily solvable) problems
+
+1) the xapian database holding email indexes can grow to be quite large;
+user may have large space for emails (somewhere else than HOME) but small
+HOME. This can be "fixed" by keeping the database still in the same hierarchy
+as email files. Making user to point XDG_DATA_HOME elsewhere is (I) global
+and (II) fragile for an user to do.
+
+2) User may have multiple separate email configurations under one user
+account; This is easy to fix with environment variable; if exists,
+overrides XDG_DATA_HOME or $HOME/.local/share -- actually if this holds
+"only" configurations, the XDG_CONFIG_HOME is more appropriate
+(again, in simple case users should not be bothered to set any environment
+variables themselves, but should be able to survive with large databases).
+
+(standard disclaimer apply :)

+PS: I have not (yet) looked the other patches; been too
+busy writing code to my personal htpc environment...
