Unimplemented features: 1. Permissions for view 2. Download button 3. Mermaid 4. Separation by Data store 5. JavaDocs 6. Locales

2. Locales creation is completed (need to check) 3. DataStore verification has been completed, no edits are required.

2. Displaying system entities ability has been added 3. Is nullable, Is mandatory fields has been centered 4. Similar to Base64 algorithm encoding for PlantUML has been added

…ng filter filed input (need to discuss) 2. Search by like 3. RegExp support for search 4. Displaying intermediate tables for many-to-many relationships (LINKED_TABLE.LINKED_COLUMN) 5. Timeouts for ping diagram server

Known issues:

I had to implement details and hide the textField inside it to make the urlQueryParameter facet work correctly. This caused the markup to shift (this needs to be discussed).
Flex-grow for the Is Nullable and Is Mandatory columns doesn't work. Because of this, they are slightly wider than necessary.

No need for entity package, because you can get/set nulls for any attribute.

+        UI.getCurrent().getPage().open("datatl/data-diagram");


Add a comment, that you use UI.getCurrent().getPage().open intentionally to open a new browser tab.

May need some delegate here so that a TabbedMode can open a new application tab instead.

As for the DataTools add-on, everything is ready. All that remains is to implement mutual support from the private repository.

I still think that the Search button is redundant.

<details> is unnecessary complication and breaks layout (see the screenshot above). A simple placeholder will do the trick + you have tooltip for detailed info.

2. Flex-grow has been fixed

DataGrid provides the Selection listener. You must use it instead. Currently removing selection doesn't clear attributes

dataStoreNames can be initialized in the load delegate, before they are used

It's better to subscribe to `TypedValueChange``

Strings.isNullOrEmpty(event.getValue())

Still unclear why we handle button clicks if tooltip is shown by hover
