+Search views
+============
+
+On search views, this addon allows developers to show a predefined range of intervals. Use ``widget="date_interval"`` and an options dictionary to configure the addon, at least a type of interval. Currently, the only supported interval type is `iso_week`: ``options="{'type': 'iso_week'}"``.
+
+Configuration options
+---------------------
+
+    type
+        Possible values are ``iso_week`` (shows iso week numbers)
+
+    date
+        The reference date from which to calculate intervals if different from `now`
+
+    lookahead
+        The amount of intervals after `date` to offer to the user
+
+    lookbehind
+        The amount of intervals before `date` to offer to the user
+
+    exclusive
+        If truthy, selecting one interval will unselect all already selected intervals. If not set (default), selecting multiple intervals will yield a domain for all selected intervals
+
+    cycle
+        If truthy, the currently selected interval will be used for setting the reference date. The effect is that you can cycle through intervals rapidly in combination with `exclusive = 1` and `dropdown = 1`
+
+    dropdown
+        If truthy (default), the intervals to choose are shown as a dropdown menu

+- migrate the work done in https://github.com/OCA/web/pull/575 to 10 for the form view part
+- support tree and kanban views
+- support much more interval types (days, months, quarters...)
+- invent some textual way to fill in some interval (-1w+3w for now - one week to now + three weeks)
