Improve default suggestions at search

Situation:

Without input, the search suggests 5 recent searches and below that 5 categorys of LoPoints.

To see older recent search terms, it is necessary to delete from the 5 recent search terms. But by this, the user looses the most recent search terms. There is no other way to see a larger search history.

In the lower part of the default suggestions, a random selection of 5 categories is given in a fixed way (random, because I can not see a logic of selection/sorting).

Idea1:

Separate the recent search terms to have a larger list of recent search terms and see older entries without need to delete newer entries.

Idea2:

Let the user select his prefered LoPoint categories to be shown in the defsult suggestion list instead of random 5 entries.

P.S. this ideas can be combined with a new search without suggestions (and instead providing the functionality of recent search and favourite LoPoint categories in a standard search) 😉

What do you think about this ideas?
