V3 Collapsible sidebar: Available space in marketplace browsing context

[DrDBanner]

Is your feature request related to a problem? Please describe. According to https://gs.statcounter.com/screen-resolution-stats/desktop/worldwide 46% of all screen resolutions is smaller than 1980px of available display space. On a MacBook Pro 13" the available space is only 1440x900 even though the native resolution is 2560x1600. It's a 1,7 factor.

This leads to a visual dissonance in the context of browsing items, which is the main task. Only 60% of the available space is available to display listings.

On a 1980px display this problem isn't too evident since the ratio seems to be more like 70% of space is available to items.

Describe the solution you'd like

1. Add an optional collapse state for the sidebar
2. Refine all breakpoints
3. Take viewport height into account additionally

Rough proposal for a collapse state.

This proposal doesn't aim to be a final solution. There are multiple implications that need to be addressed as well.

General note The Particl Marketplace has to deal with multiple sacrifices due to its graphical framework made for a cryptocurrency wallet. Though, the marketplace plays the biggest role for the product. I am of the opinion the framework must kneel to the products and change accordingly. At the current state it work well for a wallet. It doesn't work well for a Marketplace, at least in the current state.

This proposal is just a little UI/UX patch but it doesn't fix the underlying dilemma.
