Summary:
This diff introduces the AppInspect pane.
I didn't get very fare, and it is markup only, but while at it made a bunch of other improvement in the component lib, so figured to prematurely submit to don't make the diffs too big.
Improvements
- Separated sidebar and Layout.X, as it was to much responsibility for one component, and made customization hard. Also caused state loss when switching between resizable and not.
- Setup a basic top level selection. Maybe will move it into redux in the future, but for now it suffices.
- Introduced Layout.Horizontal and `Layout.Vertical` as alternative to Ant design's space. The reason is that the latter can't stretching children, which we use quite frequently. (that is because they use wrappers to create spacing, but since we run on Electron, we can use CSS `gap` instead, which handles that much more elegantly).
- Fixed issue where gutter handle could disappear when dragging to far.
