Hi Hakim,
1) so you mean SQL Editor and panel with records from SELECT?
2) it is okay on our forum to name other tools and where they can be better. We like to hear any such things to be able improve Valentina Studio
3) I guess such editing of records in OTHER tool have many enough limits. Something as
* must be PK selected
* must be single table SELECTed?
because I doubt they can edit fields of join records for ONE table, for example.
4) And for single-table case we have powerful Data Editor, where exists FILTER (CMD + F)... you can easy specify the same WHERE filter to see only some records. Try this way and let me know if it is not so comfortable as SQL Editor of other tool.
Also please note that our Data Editor can work with 2 related tables. Again this can be quite powerful feature in your hands.
