This PR would break the config for all users and themes in Gallery. To avoid that, we need to keep center under alignment in the validation file. While we can consider removing it in a future version. Additionally, bar.py should still include support for center as I've seen many themes on Reddit using center: true

So validation should be like

'alignment': {
    'position': 'top',
    'center': False, # Deprecated
    'alignment': 'center'
},

I totally forgot about backwards compatibility. Should hopefully not break anything now.

OK cool, just please make sure everything is properly formatted before we merge this

        'alignment': {
        'position': 'top',
        'center':    False, # DEPRECATED
        'alignment': 'center'
    },

to

    'alignment': {
        'position': 'top',
        'center':    False, # DEPRECATED
        'alignment': 'center'
    },

Additionally, please update the documentation with the new options so we can include everything in this single PR.
Also, the default config file doesn't need to include both options, you can safely remove center: false from config.yaml. Since the new configuration format will support it, there’s no need to display deprecated entries.

Note:
Clean up the commit history, and then we can merge this into the main.

I've reverted the changes — there are way too many issues with bar position in this PR, especially when there are multiple bars on multiple screens
