pgadmin 4 3.1 retiling data output panel

In the Query Tool, when trying to raise or lower the border between Query Sql Editor and Data Output Panel it is very common that when you move the mouse over the Data Output panel's header it changes the vertical - horizontal arrow icon to a cross arrow changing Data Output panel from its default tiling to floating

What should I do to return the Data Output panel to its initial tiling mode?

In addition, Data Output panel once in floating window stops showing queries's results, it only shows the messages, I suppose it's 3.1's bug.

My solution so far is to save the query, close it and reopen it to recover its tiling mode

Cursor's disappearance problems have not been corrected in full

What is the best free competitor of pgadmin 4?

In the pgadmin browser, click on the File menu and select reset layout.

Yes, will get all kinds of warnings, but the query tool returns to being useful.

I don't know in PgAdmin 4.3, but in 4.6 I found that way to re-arrange it.

First, right-click on somewhere to Add Panel -> Scratch Pad first to get a panel holder first (when clicking, notice the highlighted light blue space),

then right-click the lower half space to add another panel -> Scratch Pad at the lower half space (when clicking, notice the highlighted light blue space),.

After that, click on the tab and hold to drag and drop to where you want (when clicking, notice the highlighted light blue space).

I have pgadmin 4.15 and I found how to resolve this. On the upper left corner, click on File dropdown and then click on Reset Layout. It will ask to restart the application, click Ok.
