I've been experiencing lately some issue editing data in the data table:
Symptoms are:
- I use "remplace" to fill the date/instrument/surveyor fields after importing my last data set, but I can only edit one... sometimes two fields before I can no longer do edits using replace
- I notice also after a few drag and drop lines in the table that I can no longer move the lines or creates new lines.
- when I close the file and reopen it... I can start editing the data but the same issues appears quickly.

I'm working on my "massive quarry survey file"... I now have about 250 000 lines (38km length) and I suspect the issue may lies with the "Crtl+Z" memory or something like that. Any edit is incredibly long, even doing what seemed to be simple tasks e.g. creating a new line in the table... I do understand my file is big, but maybe there are a few things to opimize... Maybe starting with the data management in the table to make simple operation lighter and therefore requiring less Ctrl+Z memory.
