In Bash shell doing

ls a(1).jpg

results in the error message

bash: syntax error near unexpected token `('

In Bash and tcsh (and most other shells), parentheses have to be escaped or enclosed in quotes. Wildcards must not be enclosed in quotes or they will not be expanded by the shell.

So for filenames containing parentheses eg a(1).jpg b(1).jpg, this ls command will work

ls *"(1).jpg"

or if you prefer to have the quotes just around the critical part

ls *"(1)".jpg

If you files names contained quotes (double or single), then you would have to escape the quotes themselves to list them.

The -p option only appends a slash to the name of directories.

One of my preferred options is –group-directories-first which does exactly what it says.

I’m guessing that it’s any change of the terminal window size, not just going full-screen. That will reset a bunch of spacing-related stuff, obviously including the terminal tabs set.

I’d suggest setting the bash PROMPT_COMMAND (or possibly one of PS0/PS1/PS2) environmental variable to include your desired tabs command so it’s run automatically at each prompt. See the bash manpage or info pages for the details.
