closes #564

Description

This pull request addresses two bugs related to window management within containers and one enhancement:

1. Bug 1: Incomplete Window Reorganization

   • Issue: When a window is inside a container, dragging the window sometimes leaves gaps in the tiling arrangement.
   • Discovery: This issue occurs because the container was not being added to the pending sync vector.
   • Solution: Add the container to the pending sync vector to ensure proper reorganization of windows.

2. Bug 2: Workspace Crash with Split Containers

   • Issue: When at least three windows are in a split container, moving a window (highlighted with a red arrow in the screenshot) into the child split causes an error stating that the parent has no workspace, leading to a crash.
   • Discovery: The crash happens when attempting to move the window into the workspace before setting it as a floating window.
   • Solution: Fix the issue by ensuring the dragged window is moved into the workspace before it is set as a floating window.
     

3. Enhancement: Improved Window Splitting Options

   • Feature: Previously, window splitting was limited in direction. This enhancement allows users to split windows in all four directions: top, bottom, left, and right.
   • Benefit: Provides greater flexibility in window management, allowing for more customized layouts based on user preferences.
