Finally HeidiSQL is now capable of displaying tables, views, procedures etc. in groups, or let's say folders of the database tree. Also, when you click "Tables" for example, the list on the right only shows tables. You can activate folders by rightclick: "Group objects by type":
Folders in the session manager was another thing I was working in my last 2 holiday weeks. A huge modification of many lines of code, 3 times more than for the tree folders. HeidiSQL sessions are stored in registry, in the key
HKEY_CURRENT_USER\Software\HeidiSQL\Servers\
Now, you cannot only have a session in that root:
HKEY_CURRENT_USER\Software\HeidiSQL\Servers\Online #1
but also create folders, sub folders and sub sub folders etc:
HKEY_CURRENT_USER\Software\HeidiSQL\Servers\Remote\Live\Online #1
That helps users to organize their settings in some reasonable structure, especially when having many of them. See yourself:
