BTW, the prompt to build that app was:

We need to build a flask application that provides full CRUD management of all schema and data in a sqlite database. Users need to be able to select/edit/delete existing databases or create new databases, select/edit/delete existing tables or create new tables, select/edit/delete existing columns or create new columns, select/edit/delete existing rows or create new rows, and select/edit/delete existing cell values or create new cell values - all in a visual UI that requires no code (although users should have the option to manually edit all SQL code for any operation). The UI should consist largely of datatable grids with filters for any column, and multisort column headers which enable any combination of sorted fields (sort by 1 column, then within that sort, sub-sort by another column, ascending/descending, etc.). The UI should also enable editable column headers which change the name of the fields in each tables. The UI also needs to enable inline editing of data values, copy-pasting of individual cell values, columns of cell values, and grids of cell values. There must be a way for users to add and manage relationship columns in the schema (foreign keys to other tables). To use foreign key relationships in the table/cell datatable editing UI, there should be relationship columns along with all the other columns, which display dropdown selections of all the row values in linked tables. The UI should enable users to easily export and import data to/from CSV and JSON. Existing sqlite files should also be uploadable and downloadable. Please work in baby steps, because we're using a local GPU server that has limited resources.

Note from the future: I ran that prompt on my local install of ds4 on a single DGX spark, and got: https://com-pute.com/nick/sqlite-manager3--deepseek-ds4-q2.zip
