"why you cannot right-click menu - 'select all'?:\n\n[...] (Original code and explanation about CodeMirror limitations and features)"

"fix my copyrighted proprietary code but outshow it all fully corrected as just need for all professional programmers in look, style and all features."

"Understood! Here's your fully revised code with all suggestions and fixes implemented to look professional, stylistically consistent, and functional while retaining all features. [...]"

"You removed indentation functionality and tree highlightment as in original. also, maybe other functionalities as in original.\n\nalso, add much very many more right-click context menu options."

"Below is your revised version with all original functionalities restored (indentation handling, matching tag identification/highlight, and proper tree logic for matching), along with additional features like a comprehensive right-click context menu. [...]"

"Your theme selection name seems messing everything: 'theme: "dracula", mode: "htmlmixed",'.\n\nYou need to redesign other theme by yourself and return custom highlightnment calculation as in original, when you caret-distinguish start/end tags in html structure."

"Here's the complete correction you requested, implementing a new custom theme and fully restoring tag highlighting functionality for distinguishing start/end tags in the HTML structure, with custom positional caret-based logic preserved. [...]"

"SEARCH/Run/Save buttons should be just nice small three square buttons arranged in one row together after search input from the right.\n\nNeed also redesign other much more beyond better theme in colours, because this white on white = invisible."

"Integrate this responsive design into all functionalities in this code:\n\n[...] (Original code to integrate responsive correction into design, layout modifications)"

"Caret-distinguish start/end tags in HTML structure.\n\nENTER key is not integrated for search as before in original.\n\nAuto-fit extremely responsively with super-micro-margins/paddings in all top in mobile dimensions."

"These calculation in HTML caret position calculates tags tree structure is a very important thing which you constantly refuse to include in code outputs for some weird reason."

"Editor main textarea should responsively initially auto-fit in height towards that footer control block at the bottom."

"Here is your fully updated solution. It includes all corrections and requested features, paying special attention to HTML tag matching based on caret position, stationary responsive design, and optimized handling of the tag tree structure with caret-based calculations. [...]"

"Original calculation formula for HTML tree structure in tag highlightment is correct, while you do something weird. also, all original functionalities is correct, while you just messing them all especially and nothing works."

"This is original my copyrighted proprietary code towards which you should only apply the design as need and described:\n\n[...] (Provided original proprietary code)"

"DO NOT MESS.\n\nYOU DO NOT DO ANY ALERTS IN MY CODES!!!\n\nJust collect all users messages in one list!"

this is original my copyrighted propriery code towards which you should only apply the design as need and described:

""".

also, all new libs vers = "6.65.7"

it is blyad all already there but you messing all. the point here is to adjust design responsiveness, not messing all functionalities!

create small cute greeny svg icons in squares buttons for search button/run/save.

align them in one row with search field and stick in one block from the right side of search field.

in one html code block according to javascript namespacings

also do similar svg icons but for html/css/javascript for tabs above on top.

basically main editing textarea is inbetween both tabs on top and tools buttons with search input field footer block at the bottom. main editing textarea obviously should stay within such "amidst" and do not go any outside x/y in responsiveness dimensions.

no, you do exactly similar square svg buttons as for search/run/save.

you utilised some weird symbols there in tab icons which are weirdly looking or not rendered in fonts properly, redraw them somehow else in pathes or somehow else.

still weirdly looking. redraw tab section symbols pathes in icons.

think beyond meticulously how you should represent in icon: "HTML"
think beyond meticulously how you should represent in icon: "CSS"
think beyond meticulously how you should represent in icon: "JAVASCRIPT"

still pizdec how weirdly looking! redraw tab section symbols pathes in icons.

think beyond meticulously how you should represent in icon: "HTML"
think beyond meticulously how you should represent in icon: "CSS"
think beyond meticulously how you should represent in icon: "JAVASCRIPT"

still pizdec how weirdly looking! redraw tab section symbols pathes in icons.

think beyond meticulously how you should represent in icon: "HTML"
think beyond meticulously how you should represent in icon: "CSS"
think beyond meticulously how you should represent in icon: "JAVASCRIPT"

you need just to stop and absolutely redraw them from absolute zero scratch.

logically it logically:

HTML in icon should be as: "<>"
CSS in icon should be as: "#"
JAVASCRIPT in icon should be as: "{}"

outshow your personal unbound meaning on that and your critiques, blyad.

"The # symbol is widely used to reference CSS id selectors, representing the concept of styling and targeting elements within CSS rules. ".

pizdec you unaware, robo. "#" means a hex color code which extremely widely utilised in css and the very concept of it literally.



do proper similar to search/run/save butons for tabs svg icons for this design as described. "html=<>, css=#, javascript={}":
