### 4/5 — Does the thing, but not gracefully

*2024-05-06*

First of all, the fact that this exists and is functional is excellent. 4 stars for showing up and working! 

There are a couple of areas that I would love to see improvement. First, the history should stay open if it was open for the previous page. It currently closes randomly. Second, there should be a way to rerun the previous search values on the next page visited. That would save loads of time.

### 5/5 — Works Great

*2023-09-01*

Very straightforward to use, makes searching on pages for complex things so much easier

### 5/5 — 非常好用

*2022-10-14*

macOS、iOS 都能用！

### 3/5 — mixed

*2022-07-04*

"Content script was not loaded" for
file:///..... urls;
a little odd if you mix this search
with page changes -- in my case, I deleted
messages while displaying the gmail inbox.

Some day, maybe.

New features:

3. Added Chineses localization.
4. Regex input persistent: valid or not, your typed-in regex string will stay in place till current tab is closed.

Improvements:

2. Better match result: text in shadow DOMS can be matched now. In human words: more texts on page can be matched.
3. Better keyboard shortcuts responsiveness(when connected): keep pressing Enter/Shift+Enter, selected match will keep bouncing.
4. Better scrolling: when changing selected match, auto scrolling should work better to scroll the selected match into visible area.

Bug fixes:
1. Copy matched texts functionality. This should work every time, plus no more empty lines in copied text!
2. Input regex won't be modified sometimes.
