Ok. Thanks for the answer.
I was also wondering if it is possible to have one look and feel which would be smart and fix the column width to fit the text? Probably best only in a few main columns (as tags column and some other could make it messy) - title, series, author. So that these always fit into column - width gets adjusted (might be annoying in some cases so it should be something which you can turn on and off in look and fell or something like that).
I don't know I am just throwing ideas maybe some will stick
Don't know any technical stuff so don't know what is easy or hard to do and what downsides and upsides it might have.
