The tool is well made but I have some suggestions on some things to change.
1) When you click on the "Text" field, all entries are sorted. The same cannot be said by clicking the "Id" field. Consequently, as it stands now, to reorder the entries as per default, the program must be reopened.
2) By selecting multiple entries and pressing CTRL+C you can copy the text. I would also add the inverse feature, thus allowing the user to paste text with CTRL+V.
3) I would add an option that searches for a certain string among the various entries. It is useful if you search for a specific entry quickly.
4) An option to export/import the text in txt or, even better, csv would be useful. This would allow you to edit the text using other programs, such as Excel, and then import it into the tool and save.
