In my opinion the best synonym that can replace glimpses is Views. I believe this because glimpses means to peek or sighting.
Hope this helps! God bless

An outline, also called a hierarchical outline, is a list arranged to show hierarchical relationships and is a type of tree structure. An outline is used to present the main points or topics of a given subject. Each item in an outline may be divided into additional sub-items. There is also a second definition to the word outline such as the one where there is a site that you go to clean a virus on your electronic device for free so when your given the prompt outline just write this.
