To install

Google Tag Manager

A roomier, filterable GTM

Less scrolling, less squinting, more shipping.

Full-width content area

GTM caps its layout at 1440px. Enhancer unlocks the full width of your screen — tables finally breathe on big monitors.

Type filter for Triggers & Variables

The native "filter by type" drawer exists only for Tags. Enhancer brings the same side-drawer — icons, counts, removable chips — to Triggers and Variables too.

Account / Container / Workspace at a glance

The IDs you keep looking up, pinned in the top bar next to the container ID — with bold labels.

Newest first, always

Lists default to "Last Edited" descending, so the thing you just changed is on top. Your manual sort choices are respected.

Accordion home page

Accounts collapse on the GTM home page. Ten clients, one clean list — expand only what you need.

Tag Assistant

Debug mode you can actually read

The event list, upgraded.

Auto-sized event sidebar

The left column grows to fit your longest event name — no more gtm4wp.formElementEn… Page titles get ellipsis and a tooltip.

Any dataLayer field, under every event

Pick a field — gtm.uniqueEventId, your event_name, anything — and see its value as a chip under each event in the list.

view_item_list

Floating control panel

Change the displayed field and hide noisy events (Container Loaded, Message…) right from the debug window. Preferences persist across sessions.

Clean scanning

While Enhancer reads event parameters, a spinner covers the flicker — values appear all at once, when they're ready.
