How about something like this (see attached video).
YES, that would be so, totally awesome!

I think I might even have tried doing exactly that once, out of exploration / desperation. (If you wanted to make it more obvious, you could temporarily change the hamburger to a "?" or "ⓘ" / info icon while the user is holding a piece of equipment, but that could get distracting and I don't see it as necessary myself).
2) doesn't exist (unless you are playing some other fork) ...
Are you confusing it with Ctrl+L-click?
I was, for the case of #2. Sorry about that.
- It can be considered on a few selected places based on community feedback...
- I was waiting for feedback first, but obviously nobody from the community plays on mobile, or nobody cares about it, or nobody reads the forum.
- I have a life too.
Totally fair.
I'm actually really blown away by how playable it is on Android. I've spent more than 50% of my
The X-Com Files gametime on that platform, out of convenience. And this is coming from someone who generally shuns doing things on mobile in favor of a "real" platform like desktop.
The change you made a while ago to
show filter boxes had a HUGE impact on playability. It's really nice not having to repeatedly scroll through huge lists like inventory at a hoarder base, the UFOpaedia, etc.
I feel like if it was more accessible to get started (...imagine if a deal could be cut with Take-Two or whoever to bundle the copyright IP so you could install and launch XCF with a single tap), and with a few more quality of life tweaks, that could be avenue to bring in lots of new players. I can easily state that coupled with that mod, this is the deepest game I've ever played on any mobile platform, and it certainly competes in terms of "fun factor" with other, much more popular titles I've played. I realize I might be a little biased due to nostalgia. Maybe one day I'll do a little how-to writeup with screenshots on how to install it, set up the mod, configure savegame syncing with other devices, etc.
In the meantime, the tweaks you've already made have really improved my own experience and I thank you for that sir!
I made a separate thread to list a few screens where a middle-click (and potentially right-click) could be helpful:
