Welcome to the community @o4zloiroman! You’re making quite an entrance this way, so please make sure you read the community guidelines.
Logseq being an open source project, you’re free to suggest changes and make a pull request (or just roll your own custom build). Or just follow the suggestions in this thread. I mean, if the name “Contents” is causing you so much pain…
The name Contents comes from the fact that you can disable the Journals page and define a static homepage to load when starting Logseq. By default this is the (Table of) Contents page (Alex even explained it in the post above yours).
You have to realize that Logseq was started by a group of people whose native language isn’t English. Yet, they’re still making an effort to create a free tool in as many languages as possible. Personally, I’m grateful for that even though “Contents” might not be the best name for a personal index or table of contents.
I agree it would be nice if it were possible to rename the Contents page to anything you like. But as you rightly point out, it’s a trivial thing and there are bigger fish to fry at this moment.
Sorry if I sound salty, but I wanted to give some pushback by providing context. Also, we want to keep this a friendly place so please don’t speak like this about people who put long hours and tons of energy into creating a free and open source tool for our benefit.
