I have some requests to improve usage of HeidiSQL.
1/ The PK column is shown with an icon of a yellow key.

But id we sort the column, the sort arrow replaces the yellow key, so we don't see anymore it's a primary key :(

2/ We can filter the name of the column by taping the beginning of its name.

Maybe it could be more efficient if we can reset the input by clicking in a delete red cross. Without this we have to delete input with the keyboard :(
Thank you for reading (and sorry for bad english).
