Please consider extending the "Find On Page" tool with options:
• Match Case
• Match Whole Word

Example case: I was trying to search for occurrences of "A" (amperage) on a page, but it was literally impossible to find relevant places.

Opera browser has a feature that lets you know about duplicated opened tabs. It annotates duplicated tabs with a blue bar at the bottom of the tab in the tab bar (whenever you hover over one of them). I'd like to see this feature extended to also inform me if a given link I am hovering over on a page has already been opened in a separate tab. This'd help me navigate and better organize my current workspace.

Use case example

I am researching some complex topic (with a lot of link references from the original page to other pages) which requires me to have several tabs open and reference one another from time to time. Having the requested feature would save me the effort of figuring out which sub-pages are already opened, which in turn would help to get back to the context of browsing the original page.

Switching tabs causes a strange glitch where the contents of the new tab get covered up with a view of contents of the old tab. Only after a while the view gets fixed and the proper tab content is displayed. Sometimes it also happens to be covered up by some graphical artifacts like white squares covering most of the viewport.
This is very annoying and makes me want to ditch Opera browser and use Chrome instead (which works fine).

I'd like to have more control over how history records can be removed. I'd like to select a bunch (range select with Shift+LMB and multi-select with Ctrl+LMB) and delete them all with once click. Currently, I only have an option to delete all history from 1 hour, 24 hours, 7 days, etc or if if want to selectively delete records, I have to spend a bunch of time clicking the "x" button on every entry I want to remove. This is not convenient at all.
