UI: In-game UI to toggle persistent overlays

Most off the overlays listed in Mod settings > Overlays tab correspond to buttons on the in-game toolbar.

Would it be possible to right click or shift+click (or whatever) a button on the in-game toolbar to toggle its associated overlay?

Furthermore, is it possible to overlay a border image round the tools that have persistent overlays enabled?

Extending that, would it be worth changing background colour of active toolbar buttons?

Each button would have the following sprites:

• Inactive
• Active
• Inactive + Overlay
• Active + Overlay

Code changes required:

• Handing a click modifier (or right click) on the button to toggle persistent overlay
• Displaying/changing sprites on the in-game toolbar

I could do some quick image mockups this week to illustrate what it might look like?

I think some of the existing buttons could be merged too, For example, Junction Restrictions, Priority Signs and Toggle Traffic Lights could feasibly be grouped under a single button. While the three features would remain individually activatable in mod settings, the end-user visualisation could depict them as a single feature. So you go in to junction mode and in that one interface you get:

From ‘junction restrictions’:

• Enter blocked lanes
• U-turns
• Pedestrian crossings
• Straight-on lane changes

From ‘priority signs’:

• Stop / yield / priority

From ‘toggle traffic lights’:

• Toggle traffic lights

It would require better UI for all three features, but much of that could be achieved by looking at how the vanilla junction editor (stop signs and lights toggle) works and extending that UI to include the other features/icons.

If we go down the “build bar” route (see: #51), we could have dedicated tab to toggle overlays.
