v2.31.0 (2026-08-12)

Overview

Vite Horizon 2.31.0 adds a Reset Style button to the Style Editor, so you can put a layer back to the way it was published without hunting for the original colours, widths and label settings yourself.

It also makes every reset control in Horizon red, so a button that throws work away no longer looks the same as a button that simply clears a filter.

There are no changes to how layers are styled, saved or printed.

Breaking Changes

None in this release.

New Features and Improvements

Reset Style

The Style Editor's action row now has two buttons: Update Style, which applies your changes, and Reset Style, which discards them and restores the symbols and labels the layer service publishes.

Reset Style sits second and is outlined in red, so it does not read as the obvious button to press. Hovering it shows what it does — Discard your changes and restore this layer's published style. When the reset finishes you get a short confirmation, Style reset to the layer default, and the panel's controls refresh to show the restored values rather than the ones you had typed.

Reset cannot be undone

There is no undo for Reset Style. Once the layer is back to its published style, the colours, widths, marker settings and label formatting you had applied are gone — you would need to set them again and press Update Style.

It resets the sublayer you are looking at. On a Map Image Layer, the Style Editor gives you a sublayer dropdown. Reset Style acts on whichever sublayer is currently selected, not on some other one in the same layer.

Layers Horizon draws itself keep their Horizon symbols

Some layers are not drawn with the symbology their service publishes — Horizon applies its own symbols when the layer loads. Sketch is the obvious one: a Sketch line marked as a direction line is drawn as a black line with an arrow head on it, and that arrow is not part of the published service style.

Resetting one of these layers now restores Horizon's own symbols as well as the published ones, so a Sketch line gets its black arrow back. In earlier builds a reset left it as a plain thick black line with no arrow.

Layers that cannot be reset

Reset Style is greyed out when there is no published style to go back to. That is the case for CSV layers and WFS layers: the Style Editor can style them, but they have no service symbology to restore, so the button is disabled rather than failing when you press it.

My Layers reset to your own settings

Resetting one of your saved My Layers does not fetch a service style — it returns the layer to the marker, line or fill you have chosen under Settings → Graphics Styles → MyLayer Graphics. Change that setting and the next reset uses the new symbol.

The system-managed editor layers — FPP, Plan Burn, Wildfire and Cart Route — still cannot be opened in the Style Editor, and Update Style remains unavailable for them, because their symbols are defined by Horizon rather than by you. Their style can still be reset: open the layer's three-dots menu in the Layer Panel and choose Reset Style, which now runs exactly the same reset as the button in the panel.

Every reset control is now red

Roughly 34 reset controls across Horizon — in the map editors, the analysis panels, the Filter panel, the Style Editor and Settings — are now red instead of the standard blue. Red is used consistently in both the light and dark themes.

The rule is worth knowing, because it tells you what a button will cost you before you press it:

• Red means the action discards work you cannot get back. Whole-panel resets, clearing shapes you have drawn, discarding information you have typed in, discarding styling you have applied, and Clear Cache and Reset Preferences in Settings are all red.
• Neutral blue means it only clears a view setting. Buttons that clear a filter, a search box or a slider range — such as Clear Filter and Clear Search in My Layers, or the filter reset in the Yield tool — stay blue, because nothing is lost by pressing them and you can set them again straight away.

One deliberate exception: the Filter panel's reset is red, because the query you have composed there is the work.

Under the Hood

• The Style Editor's Reset Style button and the layer list's Reset Style action now run the same underlying reset, so the two behave identically instead of drifting apart over time. The only difference is the one described above: the panel knows which sublayer you have selected, and the layer list resets the first visible one.
• Resetting also clears Horizon's record that you had styled the layer, so a reset layer prints exactly the same as one that was never styled.
