Process Filter: Load search terms from config

[stranger-danger-zamu]

Describe the feature request

I have a specific config.toml file for a dashboard monitoring some capture devices. Being able to specify which processes
are listed at launch would be great.

Additional context/details

I was thinking something similar to the disk filter. Not sure if this is a planned feature or already solved and I missed it, but the only other process filter issues I saw were about more attributes to search over.

Just to +1 to the original proposal, I can only say that being able to specify a search pattern (like cpu > 0.5) from the config and / or from the command line would be indeed great and could save users quite a bunch of unnecessary key presses :)

Today I was trying to replace my htop aliases with bottom ones.

For htop I have an alias:

alias hu="htop --user $USER"

So the alias starts htop and it shows processes of the current user only.

I was looking for a way to do the same with bottom, but couldn't find a way to make bottom filter processes by username on the command line. Then I stumbled upon this issue.

Suggestion

Bottom already has search filters, so this could be solved just by having an option (--filter/-f) to hand over search phrases on the command line.

For example, bottom would be started like:

btm --expanded --filter "user=$USER and firefox"

And it would start expanded, only showing firefox processes of the current user and one could later change the applied filter by pressing Ctrl+f.

The -f option is currently unused, so I'd suggest to add -f/--filter as options for filtering (like htop) and maybe -U/--user $USER as a shortcut for --filter "user=$USER". For the config file there could be similar options.
