check scenarios

The Taskbar* App examination, was very sobering if I compare this with PiP on my SM-P610, in which nothing is missing and that works very stable. That's why I've never used T:Float. For comparison and to fix possibly bugs of TfT (Taskbar-floating-Termux), I've this App (self-build with last updates from @agnostic-apollo) now installed on my Gigaset and tries to understand this App.

Float Readme is not very informative. The permission query after the installation is good (would be good also at T:Widget).
First, I describe the check scenarios. The Float App is positioned on the Start Screen between Termux and Widget, so Termux can be started with all three Apps.
The normal OTS open X11 with some XClients so that XServer and sshd Services exist and uniquely the process environment is logged. When Float starts from the start screen again, a fixed quarity picture appears without Extra-Keys (EK) but with OS-KB. The process list is supplemented by a bash that does not appear like widget processes in the Drawer process list.

• Shot1. Unfortunately, it is not a nomal session like you get with Taskbar and have different long tap behavior: In addition to missing EK, there is no DRAWER possibility and long tap (inside - not at the top) allows move and scallation (Pinch) with appropriate instructions (good) but no clipboard. The movement beyond the screen, as with taskbar does not work.
• Shot2 I then extended the picture portrait, started from Widget check (X11) and the turned phone and have still no chance to remove OS-KB. You see: no prompt visible, because the end of Float-Picture is outside of the screen. Move of Float is only up to the half screen possible but Float could be minimized to a circle (first symbol in border)

*) Taskbar on the one hand and Floating/Picture or Android Windows on the other hand are different topics. In the Taskbar App and with Android-with-PiP contained therein (11/SM-P610), both comes only together. On various App/Task Functions (Recent-Task-Key) gestures and much more, which has every phone, I do not go on details here and also the topic session/widget-lists currently has no relation to Float. Here are two more shots, from my Gigaset (above) without Split/PiP capability and the SM-P610:

• Shot1 (Gigaset) is with Tap on T:Float, then start of t c in Float, OS-KB turn off/on in X11 (with Extra-Keys=EK) and change to Hackers KB. Then swich Key-log on in check and tap on SHIFT+ALT+CTRL (blue). Here Float-Picture is covered by OS-KB (log is hidden but Back-Key remove it) even after pinch to the smalest high of Picture and more critical with non floating gboad-KB_. X11-EK is unusable in Float!
• Shot2 (SM-P610) Since SM-Android already covers all the features of Float and Taskbar and this can be used for almost all apps, you do not need both apps. Here Float is only for comparison and since the OS already has several task bars, I have not installed this App.
  Termux is here startet from site-Taskbar (moved to PiP) and OTS open X11 here in Background. Previously the File-App** was opened in Picture and is now shrinked to the _blue Icon (also a Taskbar by tap) between 1/2 over the non-floating OS-KB. Float deprives themself to the Picture/Task Management of the OS, so it is initially unclear, what happened, if you tap on 5 of OS-KB - what are you supposed? Both EK are not usable for Float but OS-KB for all three Apps.

conclusion and possible features

It remains: Float is 100% covered by SM-OS, a reduced variant of Taskbar-Termux-Floating and without parallel Termux, barely useful. Here is Float optically hardly to distinguish from termux. Should as announced all future Android versions have behaved the SM-OS, is unnecessary the Float development. Potentials:

• The missing/double EK administration should be replaced by a common, as with OS-KB incusive Float and X11.
• Float could also be managed through Widget, which would also solve the problems with Drawer/Session list.

More checks, special effects and misconduct with TfT and Float:

Float only have the opportunity to move the picture inside the screen at the Picture-size, but it can scaled greater than this with pinch. This has the effect that the picture can not be moved or only in one direction. Then, on the right edge, the contents are cut off the content instead of wraps and in height is the prompt often under the real screen and almost always under the non-floating OS-KB. The rotation of the phones often leads to similar effects. As in old Termux versions, the penetrient popup of the OS-KB can not be prevented.
Float does not take into account the reduction of the residual surface by EK+OS-KB. However, mostly through skilful inner and outer pinch zooms, the relavant part of Termux can be brought into the visible area. The effects can most often be bypassed long Tap pinch/move. Who that seems to be complotted, should try TfT to return back to Float.
In TfT a complete Termux with nomal behavior is used but as soon as the X11 screen is touched or with Back-Key, Termux will removed fron screen and has to reopen by Taskbar*. Move of TfT is only one time after Back-Key and _reopen: possible.
