SumatraPDF has many advanced settings to customize look and behavior.
To open advanced settings file:
Settings / Advanced options...Ctrl + K, type adv to narrow down to command, press Enter to select Advanced Options... commandThis opens a settings text file in default .txt editor. Make changes and save the file.
To reset to default settings, delete settings file. SumatraPDF will re-create it with default values.
Most settings take effect immediately after saving the settings file. Some settings (e.g. UseTabs) require closing and re-starting SumatraPDF.
Documentation for all settings is at https://www.sumatrapdfreader.org/settings/settings
Here are some things you can customize:
Tab WidthFixedPageUI.BackgroundColorFixedPageUI.SelectionColorFixedPageUI.HideScrollbarsAdvanced settings file also stores the history and state of opened files so that we can e.g. re-open on the page
Below is an explanation of what the different settings mean and what their default values are.
If you add or remove lines with square brackets, make sure to always add/remove square brackets in pairs! Else you risk losing all the data following them.
