Is there any way to edit the autocomplete library?
While it is a nice feature I find it makes some less than helpful completions
examples; OR is competed to ORDER by, IN is completed to INNER JOIN, both of which result in a lot of back spacing.
I have only just upgraded so no doubt there will be more to find.
Also the speed of the editor window (typing and scrolling) has become noticably slower, scrolling in particular is very slow. Is the only option to turn off the editor enhancements?
There isn't a way to edit the autocomplete library. However, you can add your own abbreviations which will also play in the autocomplete feature. That doesn't address your specific examples though. The development team does continue to tune the behavior for the next version, and I believe your specific examples have been addressed.
As far as performance goes, we have a draft technical paper that provides some guidance that you can try:
