Hey there! Let's tackle this issue with your Mercurial plugin in Eclipse Oxygen.3a. I've run into similar quirks before, so here are some actionable fixes you can try:

Check Mercurial Plugin Compatibility
Eclipse major version upgrades often break compatibility with older plugins. Head to Help > Eclipse Marketplace, search for "Mercurial", and see if there's an updated version specifically built for Oxygen.3a. Install the update, then restart Eclipse to see if the menu options return.
Reset Your Eclipse Perspective
Sometimes custom perspective configurations can hide menu items. Go to Window > Perspective > Reset Perspective..., select your active perspective (like Java or General), and confirm the reset. This will restore default menu layouts, which might bring back the missing Show Annotation and Another Revision options.
Manually Enable Mercurial Commands
It's possible the commands got disabled in your perspective settings:
1. Open Window > Customize Perspective...
2. Switch to the Command Groups Availability tab, find Mercurial-related groups (e.g., "Mercurial Team", "Mercurial Compare"), and make sure they're checked.
3. Go to the Menu Visibility tab, expand the Team and Compare With menus, verify that Show Annotation and Another Revision are both checked.
4. Save your changes and restart Eclipse.
Reinstall the Mercurial Plugin
If none of the above works, a fresh install might fix underlying corruption:
1. Open Help > Install New Software, click What is already installed?
2. Locate all Mercurial-related plugins, select them, and click Uninstall
3. After uninstalling, go back to Install New Software, add the Mercurial update site compatible with Eclipse Oxygen (make sure it's the correct version for 4.7.3a), and reinstall the plugin.
4. Restart Eclipse once the installation finishes.
