I wish to put in a plug for Noto Sans Semicondensed for spreadsheets, although not generally for system-wide use.

I recommend it for my Tonto2 List Maker script, which uses a spreadsheet layout. Noto Sans Semicondensed has “tabular figures,” which means you can use it in tables to align digits and decimals with simple spaces and still have the look of a proportionally spaced font for text.

Noto Sans Semicondensed is available from Google, of course, but Linux Users will be more likely to install the fonts-noto-core package.

Using TOR Browser, my user agent is:

Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0

… so I confirm that Windows is not spoofed now, if ever it were.

You can see what Web hosts see. Visit:

Alternatively you can use a spreadsheet and generate lists there.

OK, I’m going to wade in here. It occurs to me that the OP could make use of my Tonto2 Python3 script for Linux and Windows. It puts a spreadsheet-like user interface over a *.csv file or files. You just need to make a home for the tag file(s). You can make bookmark lists that way and open the embedded http:// links in your browser. You could use file:/// links for local images. You could add as many columns as you want for all kinds of tags and sort and search the values to your heart’s content.

This gets a bit messy. Here’s a python code snippet that gives you some idea what I’m up to with my Debian/Gnome desktop:

In other words, in place of your browser invocation, you want a script that applies the -new-tab option to the browser invocation and you have to correct a bunch of Gnome configs, symlinks, and MimeTypes to get that to stick.

GNOME is entirely adequate.

Yes it is except when it isn’t. Maybe there’s a reason practically no Adwaita theme alternatives ship with Debian. Maybe not. But, using Gnome, it’s the default theme or nothing. I have to admit I don’t know from themes. However, there are lots of Gnome themes available from theme peddlers.

Recently I became fed to the teeth with claws-mail, which is a GTK app. In Adwaita the foreground font color is too dark (gray) on top of the background highlight (blue). My eyesight had deteriorated to the point that I just couldn’t read the Subject of the current eMail, so I shopped for a new theme that would be … adequate. I didn’t have time to try them all.

I settled on Ant by EliverLara. In this theme foreground font color (white) on background highlight (salmon) is just barely visible. I use it only for claws-mail:

> env GTK_THEME=Ant claws-mail
