Hmm. I am not sure i want to go the direction of unifing spacing in a single new setting. I have been thinking quite a lot about it but i think i rather have a user go through each setting and then see all that is relevant that way. And then further enhance this by guides like: https://halloy.chat/guides/single-pane.html

However i am NOT against adding a ton of spacing options, we should just put it under the relevant structs, and then make a guide for "adjusting global space" or similar.

Alright. Let's bikeshed the incoming config additions here now, then.

I asked an agent to helpfully summarize the tweaks I've made and propose the config keys.

Change	Code	Unified key	Non-unified key
Buffer/pane/titlebar/input border radius	src/appearance/theme/container.rs:24,43,58 src/appearance/theme/pane_grid.rs:30	spacing.pane.border_radius	pane.border_radius
Pane title bar padding	src/screen/dashboard/pane.rs:440	spacing.pane.title_bar_padding	pane.title_bar_padding
Topic banner spacing	src/buffer/channel/topic.rs:178	spacing.buffer.topic_spacing	buffer.channel.topic_spacing
Text editor inner padding	src/buffer/input_view.rs:289	spacing.input.padding	buffer.text_input.padding
Input container padding	src/buffer/input_view.rs:528	spacing.input.container_padding	buffer.text_input.container_padding
Input row top padding + row spacing	src/buffer/input_view.rs:531,532	spacing.input.top_padding	buffer.text_input.top_padding
Completion entry padding	src/buffer/input_view/completion.rs:952,2701	spacing.completion.entry_padding	buffer.text_input.completion_entry_padding
Completion tooltip padding	src/buffer/input_view/completion.rs:963,2712	spacing.completion.tooltip_padding	buffer.text_input.completion_tooltip_padding
Command bar padding	src/screen/dashboard/command_bar.rs:76	spacing.command_bar.padding	command_bar.padding
Sidebar top padding	src/screen/dashboard/sidebar.rs:679,684	spacing.sidebar.padding.top	sidebar.padding.top
Sidebar buffer list row spacing	src/screen/dashboard/sidebar.rs:634	spacing.sidebar.spacing.buffer	sidebar.spacing.buffer
Sidebar nicklist container padding	src/screen/dashboard/sidebar.rs:610	spacing.sidebar.nicklist_padding	sidebar.padding.nicklist

How do they feel to you? (the non-unified ones)

I think thats fine, in short - it should go under the config struct it relates to.
on pane we have gap right now so you can add a spacing and padding there:

[pane.spacing]
border_radius = ..

[pane.padding]
title_bar = ...

same with buffer.text_input we want a padding there...
