[FEATURE] #574
Description
Is your feature request related to a problem? Please describe.
When there are a large number of tables in the diagram, the table list on the left sidebar becomes cluttered and hard to navigate. It's difficult to quickly locate specific tables, which reduces work efficiency, especially when managing complex databases.
Describe the solution you'd like
I suggest adding grouping functionality to the left table list. This should include features such as:
- Allowing users to create custom groups (e.g., by business module, function, or other logical categories)
- Supporting drag-and-drop operations to move tables into different groups
- Enabling collapse/expand of groups to hide/show contained tables, reducing visual clutter
Additional context
This feature would significantly improve the usability of the tool for users working with databases that have many tables. It would help organize tables in a logical structure, making the interface more intuitive and easier to manage, especially in large-scale projects.
