I've been using Meld since years ago, and it's my default go-to diff viewer. The visual style they implemented helps me a lot to reason about how lines have been added or deleted from documents in the side by side comparison. Very neat!

The directory contents tree diff is also really useful.

I wish they made it even easier the basic case of comparing aribtrary text. Maybe it should be the default mode after opening the program, instead of having to click on a couple buttons, because I use it a lot to manually paste pieces of text. For example, logs from a server during testing, to compare what went different between runs.

Another welcomed addition would be "ignore masks". Some kind of regex input that could be used to quickly tell Meld which parts of the text to skip comparing. That way, comparison of log files could be made where a timestamps column would be ignored.

Yeah, I use it a lot, but 80% of that is comparing arbitrary text that I just want to copy-paste in. To be fair, that's just two clicks now (first click "File" comparison, then "blank comparison"), but that still feels a bit cumbersome.

Meld already supports text filters!

[j1elo]

Yes! There are text filters but those are kind of a static setting, found somewhere in the Preferences menu. When I wrote my comment I had in mind some user input that could be more interactive for one off, line based filtering. Although you are right, the already existing filter settings can be used for what I said, if one already has a regex that works fine for the current text being compared.
