plink dynamic path

I've tried to set a dynamic path to plink.exe (..\path\to\plink.exe) file but I realized they are not supported.

Do you think it could be possible to plan the development of this feature, supporting either dynamic paths or use of system variables (like %USERPROFILE%)?

A relative path to plink.exe is definitely supported. At least I just tested that successfully, with "..\..\plink.exe".

Perhaps you need an update to HeidiSQL.
