Has a great variety of themes which transfers pretty ugly application into a great looking one.
No need to install, it's available to use out of the box.
Con Intellisense is not intelligent
No intellisense for columns unless table name is aliased.
Con Can be buggy
HeidiSQL is known to have some bugs that results in crashes.
Con UI design is very bad
Generic windows form
Con No session backup
You cannot recover your session after close or even worse crash.
Con Works under Linux only with Wine
It works quite well under Wine with Linux, but you must always take notice if the last version of HeidiSQL has been tested, for it may not run at all. There are some bugs in the Wine version that can be annoying and you have to kill the program and restart it. A native Linux version would be great.
