Str*Viewer for Strava

Description

ATTENTION: Strava's recent update broke everything. I'm lucky the menu still appears but they changed how the feed works. Not sure when I'll have time to get this fixed.

Str*Viewer is a browser extension that allows you to view more of what is important to you in your Strava feed. You can choose which type of posts to see, which activities to view, and what data to view for each activity. You can even filter your feed based on athlete names, title contents, or activity description contents.

Newest features:
-filter for showing only favorite athletes on main feed
-modified the Shrink entries option to shrink the images and text of main feed entries

Recent features:
-KML export from activity page includes photos if available
-Map switching support for new Route Builder
-A bunch of new map types
-KML (Google Earth) export
-can export a simple path or virtual "tour" of the activity
-supports bird's eye, aerial, and athlete-level views
-shows athlete data (speed, HR, cadence, power) if available at each point of the activity
-Support for es (Spanish) and es-419 (Latin American Spanish)
-GPX & TCX file export for basic (non-Summit) users
-bulk uploads (more that 25 files at a time)
-segment filtering
-extra maps and map overlays for the activities, segment explorer, and route builder page

Note on maps:
Stadia and Thunderforest maps are included as options but these require API keys. Since I'm not exactly raking in donations for this code, I'm not willing to pony up for everyone else to use these. If I ever get enough income from this, I'll provide the API keys.

However, you can sign up for personal/hobby use API keys on their websites (https://stadiamaps.com/ and https://www.thunderforest.com/) and enter your key in the extension menu.
