As Tryton interface is really restricted to the format, a good improvement could be to add to Views section, some visuals, can be in table console format or embeding img, to use as a cheatsheet for common examples views (groups, colspan, cols, contexts) but also with some tricks like: <group colspan="2" col="-1" id="buttons">
.
That way a newbie could quickly see the max power we have in the interface and serve also for us as developers to quickly saw all the options to design good interfaces.
