Provide choice to power users through a reasonable set of
+ configurable and customizable features paired
+ with extensibility through add-ons
+
+
Power users, being one of the main target groups of SeaMonkey, should
+ be able to choose what functionality they
+ want to use in what way.
+
At the same time, the amount of options must be kept
+ comprehensible for users that not yet
+ accustomed to everything SeaMonkey has to offer and managable for the
+ team writing and maintaining the code.
+
Development of SeaMonkey add-ons should
+ be made as easy as possible, for example through providing similar or
+ the same APIs as Firefox and Thunderbird for add-on developers.
+
Everything normal SeaMonkey users need to tweak should be available
+ in UI preferences, things only a small
+ minority of very advanced users want to change should not be in
+ standard preferences UI.
+
Add-ons should be able to easily extend,
+ configure and customize functionality.
