?_size=10 option for the arbitrary query page would be useful

https://latest.datasette.io/fixtures?sql=select+*+from+compound_three_primary_keys&_size=10 - _size=10 does not do anything at the moment. It would be useful if it did.

Would also be good if it persisted in a hidden form field.

I'm probably missing something but what's the use case here - what would this offer over adding limit 10 to the query?

I came up with the need for this while playing with this tool: https://calands.datasettes.com/calands?sql=select%0D%0A++AsGeoJSON(geometry)%2C+*%0D%0Afrom%0D%0A++CPAD_2020a_SuperUnits%0D%0Awhere%0D%0A++PARK_NAME+like+'%25mini%25'+and%0D%0A++Intersects(GeomFromGeoJSON(%3Afreedraw)%2C+geometry)+%3D+1%0D%0A++and+CPAD_2020a_SuperUnits.rowid+in+(%0D%0A++++select%0D%0A++++++rowid%0D%0A++++from%0D%0A++++++SpatialIndex%0D%0A++++where%0D%0A++++++f_table_name+%3D+'CPAD_2020a_SuperUnits'%0D%0A++++++and+search_frame+%3D+GeomFromGeoJSON(%3Afreedraw)%0D%0A++)&freedraw={"type"%3A"MultiPolygon"%2C"coordinates"%3A[[[[-122.42202758789064%2C37.82280243352759]%2C[-122.39868164062501%2C37.823887203271454]%2C[-122.38220214843751%2C37.81846319511331]%2C[-122.35061645507814%2C37.77071473849611]%2C[-122.34924316406251%2C37.74465712069939]%2C[-122.37258911132814%2C37.703380457832374]%2C[-122.39044189453125%2C37.690340943717715]%2C[-122.41241455078126%2C37.680559803205135]%2C[-122.44262695312501%2C37.67295135774715]%2C[-122.47283935546876%2C37.67295135774715]%2C[-122.52502441406251%2C37.68382032669382]%2C[-122.53463745117189%2C37.6892542140253]%2C[-122.54699707031251%2C37.690340943717715]%2C[-122.55798339843751%2C37.72945260537781]%2C[-122.54287719726564%2C37.77831314799672]%2C[-122.49893188476564%2C37.81303878836991]%2C[-122.46185302734376%2C37.82822612280363]%2C[-122.42889404296876%2C37.82822612280363]%2C[-122.42202758789064%2C37.82280243352759]]]]} - before I fixed simonw/datasette-leaflet-geojson#16 it was loading a LOT of maps, which felt bad. I wanted to be able to link people to that page with a hard limit on the number of rows displayed on that page.

It's mainly to guard against unexpected behaviour from limit-less queries though. It's not a very high priority feature!
