Hi, @coises and *All, You said : I’m still working toward finding a design that is efficient for power users, obvious for casual users, and predictable for everyone, while remaining visually appealing. Good luck in the quest for this Holy Grail !!! Now, is the following behavior a bug: I previously checked the Bookmark lines when marked text in the Tools menu Then I do a simple selection of some lines of text I use the Mark selected text option ( or Ctrl + M ) => Only the first line of the selection is bookmarked ( instead of each line of the selection ). It’s also the case if the file contains previous marked text and if I use the Ctrl + Shift + M option You said : (It might seem silly, but running out of letters, I spent some time thinking of a way to use “p” before I came up with “Expand” for this option. “P” was one of the few letters that was unused in both upper and lower case … OK. So, perhaps you’ll agree with this new wording Expand to one more line before and after, waiting for the Shift(details) option. Allow me to propose Expand to five lines before and after    Ctrl + Shift + P. This would be a good compromise ! You said : I’ve been a little uncertain how to handle bookmarks. I don’t generally use bookmarks in Notepad++ at all, so I don’t have much sense of how people use them. Unlike you, I use bookmarks very OFTEN to isolate or delete portions of text. After marking some text, I mainly use the context* menu by right-clicking within the bookmarks margin. For example : I mark and bookmark sone lines of text for a specific occurrence. Then I copy all these lines and paste them in a new tab for further review I mark and bookmark sone lines of text for a specific occurrence. Then I can either delete them or delete the non-bookmarked lines I mark and bookmark sone lines of text for a specific occurrence. Then I cut them and paste all these bookmarked lines in an other location of the same file After a sort, I mark and bookmark the duplicate lines of a file. Then I have two possibilities : I delete all the bookmarked lines in order to keep only the unique lines I invert the bookmarked lines and copy the unique lines in a new tab for further review There’s just one option that I rarely use : the Paste to (Replace) Bookmarked Lines which replaces each bookmarked line by the contents of the Clipboard ! There’s one thing that bothers me about your “Invert marked text” option : Let’s imagine the text, below, pasted in a new tab : bla blah This is the test to do bla blah test bla blah Select the N++ Show All Characters option Mark, with Search++, the two words test Now, use the option Invert marked text : The first line of the file is wrongly bookmarked ( bug ? ) The two line-breaks, after each word test, are also bookmarked Compare by pasting the above text in a second tab, use the native N++ Mark command and then the Invert Bookmarks option of the Bookmark margin context menu ( In fact, an Invert Bookmarked Lines option ). Thus, I think that you should add the Invert bookmark lines option, in the Tools dialog. Then : By using the Invert bookmarked text option, the results would be the SAME as they are now ! And the present bookmarks would remain as is. By using the Invert bookmark lines    Ctrl + Shift + L, the bookmarked lines would be inverted, but the marked text would remain as is, like with native N++ ! Best Regards, guy038
